As a interesting aside to this, try an experiment I have done a couple
of times.  Rig up a way to project a high dispersion solar spectrum
on a piece of paper and take it to work (school).  Have your friends
draw lines dividing what they "see" as "the colors" of the spectrum.
Don't let them see each others work beforehand.  You will probably
be amazed at the variation.  Personally, I see   fair amount of violet 
AND blue, a very narrow region I would call green, a wider one that is
yellow and LOTS of orange and red.  Others disagree with me (and
each other) wildly.  In some cases the range given a particular
color name may not even overlap between two individuals.

During an observing run at Kitt Peak in May,
we picked up a couple of satellites on some
frames taken with a prototype Infra-red CCD
camera.  As this was "first light" for the
camera, I am curious what satellites they
were and very roughly how bright they might
have been (visually).

Both observations were made on 12 May 1992.
The first satellite was traveling roughly
NW to SE (or SE to NW), and picked up at
around RA: 17h 15.5m, Dec: +43d 32m (1950.0
coordinates), at 07:36:54 UT.  The other
satellite was traveling NE to SW (or vice
versa), passing through RA: 17h 15.5m,
Dec: +44d 58m (1950.0), at 07:38:00 UT.

Kitt Peak is located at longitude 111d 36m W,
latitude +31d 57.8m N, altitude 2120 meters.

Thanks...

I suspect that what we see as 'blue' is really mainly the blue cones stimulated
with a little stimulation of the green.  Violet is the blue cones with
virtually no green stimulation.  The response curves of all the cones are
somewhat bell curves.  You'll notice that at both the red and violet ends there
is a large range of wavelengths that are perceived as pretty much the same
color by most people since once the response of the green cones goes down to
pretty much zero there is no differentiation other than wavelength.  For
example 6500 and 6900 A may both be pretty much the same 'red' since the green
(and blue) don't see them at all so the only difference is intensity (it takes
more of the 6900 to be as bright as less 6500)

Perhaps this was at a point where there was virtually no stimulation of the
blue (or green or red) cones yet the rods were still perceiving the color
so it appears to you as grayish.

BTW, I read somewhere the human retina does respond well into the ultraviolet
yet the lens itself filters out the UV, so we don't "see" it.  But people
who have artificial lenses do see UV.  Don't know how true this is.

>And what is the color "indigo"?

Between 'blue' and 'violet', probably caused by stimulation of the blue
cones with just a little stimulation of the green, less than for 'blue' but
more than 'violet'.

Vision is a complex thing.

Indeed we have a proposal to look at Toutatis with the Space Telescope. 
Basically we would take one orbit of images with the planetary camera
followed by one orbit of low-resolution spectrophotometry with the Faint
Object Spectrograph, and repeat the sequence a couple of days later. 
The observations should fall around December 8 and 10.  At closest
approach it will be about 0.2 to 0.3 arcsec in diameter, at a crescent
phase!  Keith Noll of STScI is PI, and Alex Storrs, Hal Weaver, and I
are co-Investigators, along with Arthur Whipple of the University of
Texas.

I am sad to say that the program looks rather iffy at the moment.  HST 
is capable of tracking the object, and there is no health and safety
issue, but the observations are looking like a nightmare for the
Planning and Scheduling people, and they may be forced to veto it.  We
should know by the end of the week.  Keep your fingers crossed.

PS:  Groundbased observations are needed!  Especially in early December
the phase and aspect angles will be changing very rapidly, and we
particularly need good lightcurves.  People will be working from Arizona,
California, Hawaii, Italy, and maybe Japan, but the longitude coverage
will still be spotty.  If you can contribute, I can put you in touch
with other groundbased observers.  You don't need a big telescope, but
you do need a good photometer, photometric skies and the ability to
track a fast-moving object.  (If you can't do photometry accurate to
0.01 mag, please don't bother).

The Astronomical Society of the Pacific just sent me a catalog.  I
don't know how I got on their list, but they sell Voyager II (Mac).
Their price is $159.95, and they can be reached at 415-337-2624. 

> could someone please post the publishers name, as well as any reviews
> that might have appeared here on the net?

Some points from the catalog...

o Recreates the sky for any time and location on Earth or from anywhere
  in the solar system.
o Prints star charts.
o Animates motion of objects.
o Uses but does not require color displays (8 bit).
o Includes dozens of PICT images.  More can be added.
o Draws screen up to four times faster than the previous version.
o Works on Macs from the Plus up.  Minimum 1 MB RAM.

If anyone one the net has this, I would still like to hear a review.  Also,
a discount source would be interesting.  Ditto for Distant Suns.

Also, the AS catalog lists a program called MacAstronomy 2.0 for $69.95.
From the picture, this program appears to be the same thing as Expert
Astronomer, sold for $29 from MacWarehouse.

The best explanation for how orbiting bodies are freefalling I ever saw was
a film they showed us in about 4th grade. First they showed that a ball
rolled off a table falls in an arc. Then they drew a circle to represent
the Earth and drew a (very) tall mountain at one point. They then shot balls
off this 'mountain' and showed that because the Earth was curved the arc
would make the ball go farther (since the Earth curves away).

They shot the ball with greater and greater force and the ball went further
and further around the globe. Finally they showed that they could shoot
it with so much force that the Earth keeps 'falling away' before the ball
can land so it never lands.

If you are hoping for some relief when the House and Senate bills are
reconciled, you should read the guest editorial by Rep. George Brown
(chairman of the House Committee on Science and Technology) in the
September issue of American Journal of Physics. He has consistently
been one of our good friends.  It is difficult to try to summarize
such a clear argument, so I will just paraphrase some conclusions.  He
argues that the societal benefits of science have largely been
illusory (rather, serving as bridges from one problem to the next),
that scientists need to acquire a greater objectivity about science.
that science does not exist in a vacuum and must consider the larger
goals of society such economics and justice (the deficit), and that
scientists must use this objectivity to work out with policy makers a
new system for planning expenditures on basic research.  If such a
thoughtful, knowledgeable friend is making such arguments now, what
can we expect from the rest?

 I) I don't think this is factually correct.  Most of the reports I 
    hear indicate that the budget the president submits is usually
    the one enacted.  A few billion dollars are shifted here and 
    there, but the broad strokes of how money will be spent are 
    quite similar to what the president proposes.

II) If it really is the Congress' fault, note who elects Congress.
    So, carry this to its logical conclusion...who's fault is it 
    that the U.S. Government spends huge sums on entitlement 
    programs, social spending, and the like.
