From: mgw@resource-intl.com

Fremont Peak Observations, November 9, 1996
As was the case a week prior, the day began favoring a night at home,
reading about, rather than doing, astronomy.  The cloud cover was nearly
solid as I began my drive down highway 85 toward the little town of San
Juan Bautista.  Today, I packed an extra telescope for a friend, so the
Mercedes sedan contained my 14.5" f/5.6 truss tube and 10" f/5.6
Dobsonians.  The telescopes were in their disassembled component parts:
the 14.5" primary box and rocker box in the back seat, its upper tube
assembly and poles in the trunk (boot)... the 10"  dob's sono- tube
reclined in the front passenger seat and extending to the rear window
(this is quite a sight for other drivers on the road, since the sono-tube
is colorfully tie-dyed).  Sharing the passenger compartment with me and
the scopes was a folding chair, large folding cot, sleeping bag, clothing
box, eyepiece box, star charts and pillow. The upper tube assembly and
poles for the 14.5" and the rocker box for the 10" were in the trunk,
along with an observing table coat-bag, ladder, step-stool, and an
ice-chest with cold drinks.  I was not crowded in the driver's seat, but
there was no wasted space in the rest of the vehicle. 
The drive south was uneventful, the clouds remaining thick and still. 
Turning off highway 101 to 156 is where the enjoyable part of the drive
begins.  Two miles through rolling hills dotted with grazing cattle to the
turn onto state route G1.  Past a few homes, then the road begins an at
first gradual ascent to Fremont Peak State Park alongside a stream,
between rising hills covered with granite boulders.  Soon, the road begins
to twist and turn, climbing more quickly.  The trees this time of year are
golden and red leafed, strewn with hanging Spanish Moss.  The undulations
of the road, coupled with good music, speed, and nature's seasonal display
combine to make the trip to Fremont Peak worthwhile regardless of the dim
prospects for a successful evening of observing. 
Eleven miles later, I arrive at the parking lot, passing one member of our
party waiting in a lower area of the park for other participants to
arrive.  My car comes to a stop with the leaves of Autumn swirling behind
me.  No sooner do I get out of the car, than the owner of a 10" dob pulls
in.  We look at the sky and remark how one of our group watched the
satellite loop of the weather, and felt the "blob" of clouds would pass by
6 or 7 p.m., but it sure didn't look good.  Then our "weather forecaster"
pulled in, along with his 7" AstroPhysics.  He is followed intermittently
by other regulars; an 8" Meade SCT, 12" LX-200, the AstroPhysics Traveller
and Zeiss/AstroPhysics 100mm f/10 (?) APO, two 10" LX-200, and 18"
Obsession, 4.5" f/4 Newtonian, Orion 12.5" dob, and a Meade 90mm
refractor. 
Everyone was lamenting the clouds.  So, in an exercise in positive
thinking, a few of us began setting up our equipment.  Blue holes began
appearing overhead.  The clouds began thinning in all directions.  Soon,
the sun was setting, putting on one of the most dazzling displays of
light, clouds and shadow I have ever witnessed.  Thin feather-like clouds
in one direction.  Flat topped ones that looked like funnels could develop
off their sagging undersides.  Sharply lined structure in ones that looked
like cream and chocolate covered stretched taffy.  Behind us, billowy pink
cotton candy clouds.  Below us, to the west, the Pacific Ocean lay glassy
still, reflecting the show in the sky.  This was a great sight, and the
bonus was, they were continuing to dissipate. 
We knew that if the night sky cleared, it would not rival the prior week,
which had the benefit of a thick fog cover over the coastal cities.  Not a
speck of fog could be seen over the ocean all the way to the horizon.  As
was the case the prior week, the observing began with Jupiter and its four
brightest moons visible just west of Fremont Peak, looming to our south
just yards away.  the planet looked very nice, the banding and moons
appearing much steadier than the week prior.  Next to Saturn, then M57. 
The sky continued to improve.  Soon I began working the Herschel catalog
with my friend who owns the 18" Obsession.  We began by picking up up
where we'd left off in Pegasus.  As usual, the first galaxy was nearly
impossible.  Why does it always start this way?  We worked Peg and Cetus
from about 10pm until 2am.  This was not an intensive observing session
though, since puffs of cloud kept interfering.  So, the star party became
more "party" than "star."  It was lots of fun.  A dozen or more people
joking, talking about clubs, equipment, observing sites, restaurants,
music (right Bill?), cars, you name it.  All this interspersed with
"hey.... look at this"  shouts as someone would get a nice view of an
object in a clear part of the sky. 
Someone e-mailed me last week, asking about visual limiting magnitude at
the "Peak."  Well, one member of our group led a "count the stars"
contest, using portions of the Great Square of Pegasus as the target area.
The only rule was that "liners counted."  I did not expect much in the way
of good results.  Last week had been much darker because of the fog cover. 
The sky looked bright to me and I had felt some nights in my backyard were
not so different from this one at the Peak.  Much to my surprise, the
results yielded a limiting mag of 6.6, which makes me wonder just how deep
we could see the week prior.  So, now I am convinced that it makes sense
to take ten minutes of the night and do a count.  Although conditions do
change during the evening, at least a reasonable point of reference can be
established with little effort. 
For me, the two non-Herschel related highlights of the earlier evening
were: 
1.  Viewing the Horsehead Nebula in the 18" Obsession.  People there had
varying degrees of success attempting this feat.  It does help to know
what dark nebulae look like.  Later during the night, Jay Freeman stopped
by and pulled it in using my 10" f/5.6 dob.  I was surprised... he and a
few others could see it, I could not. 
2.  Removing the eyepiece from the 14.5" and using Mark T's Swiss Army
Knife magnifying glass in place of a regular eyepiece, holding it over the
focuser, and clearly resolving M15.  I've got to get one of those! 
By 2am, the cloud cover solidified again.  I guess our Herschel hunt
pulled in a dozen or so galaxies.  Everyone began packing up, and soon it
was just those willing to spend the night.  Well, guess what?  By 4am the
sky opened enough for what were the best views of the night. 
I was completely in my element, since many of the bright galaxies were now
up, and the only two telescopes left standing were my two dobs.  What fun
to operate two telescopes in that sort of sky!  First was ngc 4565.  The
dust lane was easy.  M81 and 82, piece of cake.  M108, M97 (look at those
two black eyes staring back).  M53, nicely resolved.  M3, forget M53!  On
to the Black Eye galaxy....what a strange sight.... what's up with that?
;-) Leo.... ngc 2903.... what a beauty.  Next, to M65/66 and ngc 3268.  I
like the latter the best of those three.... the dust lane and angular size
are nice contrasts to the finer, smaller detail in the two neighboring
Messiers. 
Ursa Major was now up high enough.  M51.... in the 10".... okay, but in
the 14.5"  WOW!  Structure galore.  I have seen it better a few times
(high in the Sierra Nevada mountains and once on the 30" in the
observatory at Fremont Peak), but this was a very nice view.  Now, star
hop down to M101.... yep.... faint as ever.  Funny how you lose your
bearings as the season's change.... I was having trouble remembering which
star was Cor Caroli.... my jump off point for M94 and M63.  It is sure
easier when the constellations ride high in the sky, and you can see them
in their entirety. 
A quick hop over to Canis Major, a peek at the nice little open cluster
2362, then back to Leo for the belly meat.... M105, M95, M96 and several
ngc galaxies in one and a half eyepiece fields.  Geesh!  Where was it, a
knot of galaxies in Leo's mane.... no star chart, no hard disk, no RAM...
just biological memory.... right about there....  yes... between Gamma and
Xi Leonis.  How many in the area.... six, seven, eight?  Well a lot.  Just
imagine what winter late night/early morning observing holds....the realm
of the galaxies (Leo, Coma and Virgo) under crisp, clear skies.  This
stuff is great!  And there's soooooo much of it! 
To the east, Venus had risen, letting me know that I'd better catch some
sleep, or risk uselessness during daylight hours.  I stretched out on my
cot, the universe serving as my ceiling for the night.  I left the two
dobs out for the real die hards.... those unafraid of sleep deprivation. 
Soon, the sun came up and I said good-by to my observing friends for
another week or so. 
If you are interested in joining us at Fremont Peak State Park at our next
star party, send me an e-mail, I'll place you on our mailing list.  The
only requirement is that you have a desire to observe and learn.  It is a
great way to spend an evening among great men and women. 
Clear skies,

Hindsight is a wonderful thing, take Lord Byron who said of Dickens
"Future generations shall wonder why we held him so high".  Or NY Times
article on Twain which said "In a 100 years time only the 'Jumping Frog'
will be remembered".  100 years ago Jules Verne wrote "From Earth to the
Moon".   Small minds can never envisage change, they cling to the "now"
as perfect.  If you want a modern example, just look at IBMs latest
assertion that the year 2000 won't be a problem for them.

Subject: Meteorites from Mars

In the recent reports of indications of life being found in Martian
meteorites, I have not been able to find any information about how we
know the meteorites are from Mars. How do you tell that a meteorite,
found in Antarctica, originated on Mars ? Is it via chemical analysis,
isotopic composition, or what ?
I'd be very grateful if someone could help me with this.
Thanks in advance

As far as branching into another universe, that's an old SF idea.  A
good recent take-off of this was Hogan's The Proteus Operation.  If
you want to allow time travel in without branching and still avoid
paradoxes, and want to carry this to it's bitter end, there was an old
SF story about a guy who went back in time and discovered raindrops
like bullets (not being able to change the past, his body couldn't
change their original path), sandwiches that couldn't be bitten, etc.
You can go even further, because the body of our theoretical
time-traveler wouldn't even displace air, so he'd die horribly right
after arrival.  Maybe he'd even explode.  Maybe there'd even be some
sort of nuclear explosion, if the atoms of his body (and time
machine?) tried to occupy the same space as air / soil / trees, etc?
Hmmm, remember the Tunguska blast in Siberia back early this century?
Could it be?  Nah!

Thats not a science book, thats a lying book.
If you are interested in what biology *really* says about our origins then I
suggest you have a look through the talk.origins FAQs.  Please don't trust
the versions you read in creationist literature: they are uniformally

      I have been instructed via e-mail by an extremely kind scientist of
the NASA team on celestial mechanics. The idea of sun-synchronicity is
not too hard and yet very important and fundamental for many planetary
missions. My question above was related to the new images to be taken
from Cydonia and, therefore, I am posting them in sequel to this:
       "NASA's planned new images from Cydonia".

From: bp887@FreeNet.Carleton.CA (Angel Garcia)

 Following the lead at Cydonia-Zone one easily gets to NASA's planning
for imaging Cydonia (and the whole planet Mars) by the going Mars
Global Surveyor. It is said in there that the quasi-polar orbit of
MGS will be:
A) circular (or as circular as possible after aerobraking)
B) nearly 2 hours period (thus close to 12 turns per martian day)
C) passing near to martian north&south; poles (not EXACTLY polar).
D) in sun-synchronous orbit (meaning that during the whole martian
     year of operation the MGS will automatically cross the martian
     equator at almost exactly the same LOCAL MARTIAN TIME: namely
      mid-afternoon in one side and mid-morning in the other side.
Therefore, according to D), we have an extremely clever and bona-fide
planning for taking the BEST possible and needed quasi-oethonormal
images of the "Face at Cydonia". So that no skeptic about reluctancy
of imaging the fundamental martian feature from NASA's party can anymore
argue on silly conspiracies taking place: NASA remains openly in the
side of pure science: noble, honest and truth-seeker as has traditionally
been until currently.
The needed images of the "Face" are the 'right-side' (which currently
is shadowed because the 2 and only 2 images taken by Viking were both
in mid-afternoon). Now we will have pictures in mid-morning to get
good images of the right-side.

    After kind lesson from scientist at JPL the sun-synchronicity
is achieved via an oportunistic use of the oblatness of Mars: there
is a marked 'bump' at the equator (twice as much as Earth has and
due, of course, to aboriginal fluidity of these planets which created
the equatorial bump by centrigugal force in their nearly 24 hour
rotation period).
   If an orbit of satellite (both on Earth and on Mars) is not exactly
polar but close to it then at the two moments when passes near the
poles is 'atracted' by the equatorial bump in opposite senses: thus
a "TORQUE" is constantly (in every turn) acting on the satellite
and such torque produces INCREMENT of the 'angular momentum' of the
orbit WITHOUT changing its modulus. So the radius of the orbit
remains constant but the vector 'angular-momentum' changes constantly
in 'direction'. This is a PRECESSION of the orbit. Now, if scientists
can set the original orbit at such a precise angle with the martian
meridian that the amount or received torque (from equatorial bump) is
such that the precession of the orbit is nearly one full turn per
martian year... then it happens that the orbit of the satellite is
slowly turning with respect to fixed stars (precessing) at the same
rate as the north martian pole turns yearly around the sun. Thus
every day we will have almost identical relative position of the
satellite's orbit with respect to the sun: that is sun-synchronicity !.
It is automatic sequel of celestial mechanics and does not cost any
expenditure of valuable fuel of the satellite.
Of course the planned orbit (with such syncronicity) can be set at any
desired angle with respect to mars-sun line: NASA has chosen for
MGS some 45 degrees angle: to cross equator around mid-afternoon and
at mid-morning. This is clever because shadows of the "FACE" and
other monuments in Cydonia (and elsewhere) will be relatively large
and can be used to make tridimensional estimates (as Carlotto has
already done in his book). We can get images of Cydonia both at
mid-afternoon AND at mid-morning (twice a martian-day).
Since the 2-hour orbit is NOT exact submultiple of the 24 and half
hour period of martian day, the 12 sectors imaged every day are
slowly shifting day after day and will amply cover many times the
whole martian surface in the planned martian-year of operation.
   Thus a full SURVEY of martian surface which, of course, will
cover the Cydonia region more than once, for sure. Now, it is
in the hands of the 'drivers' of the project to keep good
free-space in disc at the crucial moments when Cydonia-pictures
are taken... and that is not easy due to time-delay of terrestrial
maneuvering on martian-bound satellite.
    That is about it. Good luck to you, Malin and your team... but
do not insult us anymore as cottage-business because we are far more
clever than you regarding what Cydonia means to ALL of us terrestrials.

Subject: Cirrus Minor .. info wanted
From: gdhollan@wi.leidenuniv.nl (The Acoustic Motorbiker)
Date: 11 Nov 1996 11:14:06 GMT
I am looking for more information on Cirrus Minor,
all the information I have sofar states that
`` Cirrus Minor refers to the Small Magellanic Cloud, one of the two large
   "satellite" galaxies orbiting our own, visible from the southern
   hemisphere.  The Large M. C. would be Cirrus Major.  These terms aren't
   used much, usually its just LMC and SMC. ''
IS this information corect ?
Could someone point me to a place where I can find more information on
Cirrus Minor ?
If it's not too much trouble, could information be emailed to me ?
My newsserver is not the most relaible ;(

to be honest with you though, life at the top isn't all that great. It

Shit, man, you're right. I ought to instead have gone to some anonymous

Certainly it exceeds "just life", which I believe was Cathy's point. 
However, this being would be intelligent.  Hence it would be capable of
manufacturing another of its own kind.  Hence, it would be alive.  Or
would it?  What if it had an IQ of 90 or so, and did not have the
competence to construct another of its own kind?  What if it had just
enough intelligence to subcontract the construction of its progeny to a
human corporation?  Would it be alive?  
What of the last member of a sexual species?  Was the last male Kiwi bird
"alive" after the last female died?  I would say that it was alive, even
though it could not reproduce.

After following this thread for some time I'd like to offer the thought
that I think we're "wrapping ourselves around the pole" to come up with
a perfect definition of intelligence. I mostly agree with jw, but depart
with the notion of some "magical" threshold where we went from the
finite to infinite.  I suggest that we stop thinking of intelligence in
binary terms... i.e., intelligent/not intelligent.  I think
intelligence, like most everything else, is a continuum... it has quite
a broad dynamic range.  I suggest that it is helpful to take a broader
view of intelligence... look at it from the perspective of a log scale
rather than a linear scale.  If you line up all the known species which
have existed on this planet... and try to put them on some sort of a log
scale of intelligence (e.g., neuronal complexity)... that dog of jw's
(and my cat I might add) are right up there with us.  We're no big
deal... nothing magical... but we are impressive... we are the
cumulative experience of natures experiment... we stand on the shoulders
of all species which have struggled to survive on this planet.

You'd only ever pay for one particular size for one particular
commodity.  E.g. a hundredweight of silk always weighs the same.
Likewise, a hundredweight of wool always weighs the same, though
different from that of silk.  You'll always get what you pay for.

People _did_, because wet goods containers were much more expensive.

How is our proverbial medieval farmer going to measure the contents?
He's going to use a standard container.  Probably the one designed
to hold the stuff he's measuring.  He has no means other than the
standard container to measure anything.  He probably doesn't understand
the length cubed equals volume concept.

There is (as far as I know) only one volume measure with its own name,
the liter.  It was clearly intended as the unit of volume in the original
metric system.

The mass of a liter of water is very close to one kilogram.  A more
rational system would have the mass of a liter being one gram.

I have to draw exception to the current attitude that attributes mass
extinctions to bolide impacts.  There is too little to no evidence of
this in most mass extinctions.  The K-T extinction took millions of
years  and can be tied to the draining of inlands seas, climatic changes
and the preference for fossil collection in North America and Europe.  I
am not saying a hit did not occur, only that it was not as fatal as some
say.  Ask a turtle or lizard or alligator, all cold blooded, all
survived.  Sorry I got off the subject.

Subject: Moon Phases Inverted in S. Hemisphere???
From: rsmith@clysmic.com
Date: 11 Nov 1996 16:49:48 GMT
This has been diving me crazy! I need astronomical advise ...
My question: are moon phases really "inverted" in the southern hemisphere?
In other words, at the First Quarter moon, which side is lit, the right or
left?? In the northern hemisphere, it's the right side. Is it really the
left in Australia and points south? Do the local almanacs/calendars all reflect this, or use a 
"standard" moon picture (i.e. always the right side)?
Thanks...Any help appreciated!

   I've heard stories of frogs, trapped within coal, seemingly hibernating since
they spring back to life.  How they knew there was a frog in a particular rock
of coal, I don't know.  Maybe they went around x-raying chunks. ;)
   Of course, the shows/articles on stories of this ilk, tend to be spouted
mostly from WeeklyWorldNews genre of periodical.  Heh, "Sightings", in print.
   Since you quote that there are 'tons' of REAL fossil anomalies, can you

        This part is still confusing. Can you elaborate more on the distinction
        since the confusing part seems to be, where, what range, mathematically the 
        quantization occurs for free wavepackets. Does 'hbar' enter the picture only
        as an empirically derived proposition or is is mathecally derivable from
        EM constants. I've read nothing to this effect so far.
        The wave-packet definition I'm working from being:
              E'=E * integral { dk * f(k) * e ^-i*(wt-kx) }
        f(k)=a gaussian spectral funtionof the wave-number k, w=c|k_o|,

        I guess this is the case when the source is switched on and off and
        the resulting wave packet contains energy larger than one hbar*w_o
        yielding many coherent, phase-related photons ?

        And  this matches what I'm reading in terms of locating the photon in
        some symmetric region k +- delta k/2 by treating the abs-squared 
        spectral function f(k) as the probability density P(k) for the wave-number 
        lying within the region.

A photon is used in physics to explain certain properties of light.
The best explanation of a photon I can give is that it's a travelling
packet of energy with no mass but can exert a force on the medium it
interacts with.

In the July 1995 issue of "Astronomy and Astrophysics", astronomers 
Daniel Benest (Nice Observatory) and J. L. Duvent (Longjumeau, France) 
present evidence that indicates there to be a 90% chance that in fact 
three stars  make up the Sirius complex.  By analyzing all available 
measurements of the positions of Sirius A and B, they found that the 
stars did not follow perfect elliptical orbits around one another.  
Instead, it appeared as though an unseen companion perturbed their 
orbits, by about 0.055 arcseconds with a 6.3 year period.
From the observed irregularities, they compute that "Sirius C" is no 
heavier than 0.05 times the mass of our Sun - a prime candidate for a 
dim red or brown dwarf.  It would never appear more than 3 arcseconds 
from Sirius A and have a magnitude fainter than 12.

I have never understood why this is supposed to be a problem.  When
a solar system forms, the high-angular-momentum stuff naturally
goes to the outside, and the low-angular-momentum stuff to the
center.  How could it be otherwise?

There isn't much coupling between the rotation of the sun and the
orbits of the planets in the solar system today, certainly not
outside the orbit of Mercury.  The earth's rotation is being progressively
slowed by our large moon, but that's hardly "driving and controlling".
For Mars or Jupiter, the effects of their satellites on the planetary
rotation are negligible.

The equations box on the AD web page has 
m = m1/sqrt(1 - v^2/c^2) for relativaty and works for Mercury.
and
m = m1*sqrt(1 - v^2/c^2)  for AD and does NOT work for Mercury?
Why are these equations shown if they are not intended to be compared?
It's rather hard to have a superset of something if the equations are the
inverse of the set.
In fact a brief review of set theory as learned in junior college would
show this to be impossible. Perhaps the degree in advanced calculus
precluded set theory.

You don't.
As for yours, it implies the use of "standard" equipment. Would not such
apparatus be widely available at a good university. I would suspect this
type of work is done at the graduate level if not lower.

If time travel was possible and you could go into the past and alter it,
i.e. I went back and shot my grandad, Then I would no longer exist to
kill my grandad, but if I did exist then I did kill my grandad. So both
things have happend ( there would be an infinate interchange between my
existance and nonexistance ) so a paradox wopuld be set up and the time
relative to the universe would stop.  So it would be possible to alter
history but at a great expense to where the alteration occurd.
