Subject: Re: (utah-astronomy) RE: Leonid watch

Hey Chuck, sorry to have to be the bearer of bad news, but I was ale to
observe a few Leonids for two nights in a row from my very light polluted
front yard (limiting mag is usually around mag 2.5 - 3.0)On the 17th from
12:53am - 1:33am I saw 11 very nice Leonids and 1 sporadic, all but two of
the Leonids left long and very bright green trails! I also got in a few
observations on the 18th from 1:09am - 1:52am I only saw 7 Leonids and no
sporadics but all the Leonids were at least mag 1 or brighter and they were
very active around the Auriga/Gemini/Taurus area of the sky, had one very
bright Leonid about mag -2 pierce the Pleiades right down the middle, all
these had that green trail as well! Very nice to see since this was the
first time I was able to see the Leonids at all, I guess working the night
shift has its rewards, I'm really surprised that you didn't see any at all
but the 18th was definitely slower for me than the 17th, I wish I had been
able to stay out longer but it sure was cold!

Howard

I'm glad someone saw something.  I watched from the
backyard from midnight till a little after one, and
saw NOTHING!  Not one meteor.  I had told myself that
if activity warranted it, I'd stay out longer.  But I
saw NO meteors AT ALL!  I'm speculating that they were
there, but couldn't punch through the light pollution.
 Still, in one hour, I should have seen at least one
bright sporadic.  All I have to show for it is a cold.

Please don't tell me the sky opened up ten minutes
after I went in!

Hey Astro-folks,

I had to work the night of the Leonids, but counted 17 of them from the
jumpseat of a DC-10 on my way home to SLC later that night, despite going in
and out of cloud for the first half of the trip home.  Earlier, during the
peak, I was too busy to look up.

The night before I showed my crewmates the ISS as we passed Pueblo, Colorado
and it passed in front of Cassiopeia.  They were pretty skeptical until it
appeared ontime and exactly where I said.  Got to love that heavens-above.com
website.  Take a look and print out the "easily visible satellite passes" for
an evening.  For some reason this just amazes people.  Then you can casually
say, "aw, it's just rocket science."  Way cool, and an excellent way to get
people to look up.

Mr. Dunn wins the award for best place to view the Leonids (in the hot tub).
I think it would be a major step forward for the Salt Lake Astro Society from
now on if he brought his hot tub up to all the Little Mountain star parties!
That, and some good music, oh, and maybe we should start catering these
affairs?

I counted 8 from about 12:05 to about 1:25.
What surprised me is that they all were going from East to West or West to
East.
I was viewing from my back deck which faces the East and took advantage of a
large tree to block out the moon.

Does this have the cubed foam? I found the same case a Harbor Freight
for a similar price ($20, I think), but it didn't have any foam in it.

It was difficult to tell with the clouds last night,
but the way the northern sky was lit up from my home
in Lindon, and the column of light that extended
straight up from the pole (also difficult to
distinguish from a cloud), looked suspiciously like
auroral activity to me.  Did anyone from darker skies
see anything last night (Saturday)?

Subject: (utah-astronomy) Scope and Dome for sale and Tube for free

As a few of you know and most don't I have accepted a job with
IBM in Beaverton, Oregon (yeah, yeah, I know about the rain
and clouds, but it is a good job.)  Anyway I have a couple of
things I would like to sell and one I would like to give away
before I leave.  So . . .

For Sale

1) Orange Celestron C8
   Super Polaris mount with Sky Sensor computerized drive
   Celest-ease
   8x50 polar alignment finder
   2x Barlow
   25mm Orthoscopic eyepiece
   Desert Storm Shield scope cover

This is an 1980's vintage C8.  Although not the best C8 OTA ever made
it is an OK scope.

In addition to the 8x50 polar alignment finder
the Super Polaris mount has a polar axis alignment scope built in.

The Sky Sensor was an early attempt at a computerized, goto scope
drive; it is very power hungry and becomes inaccurate if
asked to do a long slew.  However, it tracks just fine and goto's
OK over limited distances.

The Celest-ease is an accessory bolted to the back of the OTA.  It
includes an 1 1/4" visual back on its back, a 2" visual back on
its top, a diagonal mirror that flips in and out to direct light
to either visual back, and a telecompressor and barlow either
of which can be flipped into the light path to the 2" back.

The whole lot can be yours for only $1500.00, but contact me soon.
I will be leaving for Oregon very soon.

2) 8' fiberglass radar dome still in its original shipping crate.

This thing weighs very little (maybe 50 or 60 pounds.)  There is
no slot yet but this could become a nice (little) dome for the C8.

$200.00

3) Telescope maker special.  A piece of heavy duty fiberglass
tubing.  20 1/4" ID, wall 1/4", 50" length (I don't know the
weight but it is quite heavy.)

Free to anybody who thinks they can use it and wants to come pick
it up.

Subject: (utah-astronomy) astro-ecconomizing

Next time someone complains about the high cost of
astronomy hardware, remind them that a little shopping
around can really pay off.  I just picked up a 2X,
1.25" brand-new barlow on Ebay for $11 total, shipped
right to my door.

A 10" full-thickness pyrex mirror, good to at least
1/8 wave, cost me $125 last year.

A pair of 70mm binoculars was found on the net two
months ago, brand-new, for $97.

My friend Glen Warchol picked up a TeleVue Ranger tube
assembly for $200.  A TV Plossl for $25.

The bargains are out there, but you have to look for
them!

Anybody else have a great deal they'd like to crow
about?

Chuck

The problem with TV programming, like printed media,
is lack of time (or space), so something will always
have to be left out.  Heck, I've been into astronomy
and physics for 30 years, and I'm probably too stupid
to understand the details myself!

The universes' expansion has something to do with
"vacuum energy", which is a quantum effect, not part
of everyday Newtonian physics that define the world of
humans.  As the universe expands, the vacuum energy
increases (there is more vacuum. Don't ask me how you
can have more of "nothing".)
Careful auditing of the detectable mass in the
universe has shown that there is not enough mass for
the universe's expansion to eventually halt, and
reverse.  Accelleration, (or, more accurately, the
"cosmic constant") IIRC, is a prediction of Special
Relativity.

Perhaps a physicist on the list can fill in the
details.

This site has many questions and answers related to
cosmology.

You will probably not get an intuitively
understandable answer, since the mechanisms at play
seem to be part of a non-Newtonian structure.  The
explanation is usually page after page of derivations,
integrals, and assorted curves, all based on tables of
variables only hinted at in the data!  This is one for
John Sohl at Weber to field!

Subject: Re: (utah-astronomy) Re: Runaway Universe

OK, my first degree is in experimental physics and I have been following
this stuff since it was announced so I'll take a crack at a simple
explanation of where this stuff came from and where we currently are
(and also my opinion of it.)

The theory is based on two different groups studies of very distant
type 1A (I think) supernova.  This type of supernova is thought to be
a good "standard candle."  That is, they are thought to ALL be
approximately the same absolute brightness when at their peak.  The
studies were done to attempt to measure the "Hubble parameter."  This
number is usually called the "Hubble constant" but that is silly since
it is not a constant.  The Hubble parameter is the expansion rate
of the universe.  The expected result of the studies was that
the Hubble parameter was decreasing and lots of interesting things
(like the age and weight of the universe) can be determined by
measuring what it currently is and how fast it is decreasing.
However, unexpectedly both studies appeared to show that the expansion
rate is actually increasing.

If this is really happening we obviously need a replusive force to
make it happen.  That's where the vaccuum energy theories have come
from.  It's just people trying to think of ways to make it happen.
As yet there is no direct evidence for this or any repulsive cosmic
force.  It's just infered from the supernova studies.

OK, now my opinions.  This stuff is real interesting and exciting,
but is the accelerating expansion a "proven" measurement?  I don't
think so.  There seem to me to be several assumptions in these
studies.  The top of this list is whether or not supernova
billions of years ago (with a probable different mix of elements)
are the same brightness as modern ones, also there are questions
about both galactic extinction and intergalactic extinction that
far back.  If the results had been as expected these assumption
would still have been worrying, but with such an unexpected and
counter-intuitive result I think all the assumptions need to
be suspect not just the one.  Now does that mean that I don't
believe the accelerating expansion theory?  No, it just means
I am not convinced yet.  I need to see some other measurements
using techniques other than supernova measurements.

Hope that helps.

Subject: (utah-astronomy) Re:  Runaway Universe

Mark's point about "standard candles" is well taken.
Even a small variation in luminosity can result in a
large uncertainty over cosmic distances.

Old stars are typically simple as far as their
constituent elements, and small.  They do not go
supernova; only fairly young, very massive stars do.
When we observe a supernova in a distant galaxy, we
must remember that we are looking back in time, when
there were not as many "heavy" elements present in the
universe.  Often called "metals" by astronomers,
elements heavier than helium were not made during the
Big Bang, but are the products of stellar evolution.
Those early supernovae were very different, as far as
their makeup, than close-by, recent supernovae.  The
far away ones are chemically simple, the closer ones
(and thus recent) must be made of recycled material,
therefore more complex.

I've read that globular clusters contain some of the
oldest stars, I've also read that they contain many
massive stars.  Obviously they are two distinct
"generations", and therefore must be very different as
far as makeup.

Does anyone know of an observed supernova in a
globular cluster?  (Milky Way satellite or otherwise).

As far as long-term observation of cosmological
phenomenon, there can't be any such thing.  Even if
humans live for another million years before becomming
extinct,(highly doubtful) that span is "the blink of
an eye" in absolute terms.  The sun wouldn't even be a
fraction of the way around it's orbit of the Milky
Way's center.  IIRC, one orbital period is something
like 225 million years!

I think that is why scientists must resort to
statistics, hoping that there are examples of every
stage of galactic, stellar, and regional cosmological
evolution scattered around the sky.

Hey, a real discussion!  Lets keep it up!

Chuck

While we're mentioning the assumptions cosmologists make when they look at
the universe (the "standard candle" being but one prime example), let me
ask your opinions on what seems like another big assumption: that the
space between us and distant objects is uniformly empty.

I've heard a few things about "dark matter", so I wonder: does anyone have
a scientific "handle" on the non-glowing stuff?  Is there any way to
detect or measure it?  (How could one detect non-radiating matter which
lies millions of light years away?)  When measuring the luminosity of
distant objects, can we be sure that we're seeing "unimpeded light" from
the source?  How do we know we're not seeing things through a
not-necessarily-uniform intergalactic fog?  Is there some technique which
allows us to "factor out" potential dimming effects?

Cheerio,
Chris

Hmm...I don't think that assumption is made in
professional circles.  Intervening material (dust and
gas) can be inferred with spectroscopy.  Non-radiating
material between observer and object is detected by
the absorbtion lines present in the objects spectrum.
True, it takes some detective work on the part of the
researcher to discern lines related to the object
itself and any intervening material, but it can be
done.

There are two kinds of "dark matter":  Baryonic, that
is, the stuff that you, I, and stars are made of; and
non-baryonic, the nature of which hasn't been
determined by science as of yet.  So far, non-baryonic
matter is just a "place holder", until it can be
detected directly.  Right now, it's existence is only
inferred from orbital velocity studies.  Example:
Stars in the spiral arms of the Milky Way are moving
too fast in their orbits to be retained by the gravity
of all the visible matter in the galaxy.  Yet they
stay in orbit.  There must be more mass to the galaxy
than we can currently detect, unless Isaac Newton was
dead wrong, which is doubtful.

Reddening, which is a scattering effect of space
particles and gas, and absorption lines in spectra
(see above)

Mark Dakins, I'm counting on you to keep me honest!  I
only had two years of college physics, and since it
wasn't my major, they didn't use Pavlovian teaching
techniques!

Subject: (utah-astronomy) Color perception

A few years ago, I noticed that my color perception is
not the same in each eye.  My right eye sees blues
much more muted, and greenish, than my left.  Also a
bit dimmer.  Strange, since my right eye is dominant.

When I posted this to the atm-list this morning,
another member sent me this link, which is truly
fascinating.  Check it out when you get a minute:
