Since this data is from NED, it is most likely from Zwicky (the MCG)
and thus the magnitudes are photographic.  A very rough
conversion is to make them about 3/4 of a mag. brighter.  But...

This is why amateurs need to start using surface brightness' instead
of magnitudes.  Perhaps the best source of surface brightness's is the
RC3.  

I did see one of the Leo dwarf galaxies with a 31-inch f/7 newtonian
a few years back.  It was only a brightening of the sky background 
as we sweep the telescope over the field.  More recently, I was able to
pickup the Ursa Minor and Draco dwarf systems with a 10-inch f/5.6 newt.
on a very good (for Ohio)night at 45x - again only by a slight brightening.
The moral of the story is that you never know until you try!

All observations were made from London, Ontario, Canada at lat +43 N and long 81 W. 
Perseids refer to the number of Perseid shower meteors seen during the
stated interval and total refers to the total number of meteors both
Perseid and other seen during the interval in question. Lm is the faintest
star visible in the field of view the observations were made in and F is
a correction factor for obstructions, clouds etc. Teff is the effective time
in hours during the interval that I was actually looking for meteors - ie.
taking into account breaks and other dead time.

I would be very interested to receive other people's observations of the 
Perseids, particularly around the time of maxima with similar data via
email at the address below.

	Don't be a sore looser Mike (spoken friend to friend)

	This observation is of a rare and unusual type.

	Actually, now when I'm asked can sun spots be seen with the unaided
eye I can say YES I got a report from someone who did it. Also I've wondered
if I could see one through the morning fog. Now I'll try it. And lastly,
this observation confirms the notion that pre-optical aid astronomers could
have noted sunspots and will give the archeo-astronomers more clues as to the
suns activity based on the writings of the greeks, chinese and the rest.

     If a model is induced from some observation or experiment, as most
models are, then it tries to predict something new and not previously known.
But if it also, completely by accident, happens to predict (technically,
"postdict") something already known, one would count that as a model success
provided that the "predicted" something truly had no part in formulating the
model, and does not require adjustable parameters.

     By application, if a model is derived from first principles having
nothing to do with quasars or stellar evolution theory, as is the Meta Model;
and if that model deductively and without free parameters requires in a
compelling way that nearby stellar objects of high gravitational redshift
must exist in place of where the standard model expects black holes; and if
we then note that the universe actually contains objects of the predicted
description called "quasars", one can say meaningfully that the Meta Model
"predicts" quasars whereas the standard model does not.

     In truth, the Meta Model predicts "quasars", many of which must be
relatively local objects.  If it is discovered (or perhaps I should say
"confirmed", since there are already early indications from VLBI) over the
coming decade that many quasars have significant proper motions, then clearly
those quasars are nearby as predicted by the Meta Model, and not all at the
cosmological distances required by the standard model.  So the quotes could
then be removed from the word "predict" in this connection.  -|Tom|-

The vast majority of comments I got were favorable of posting ANY
observations so long as they were short and the format used
was plain text, not a form which wastes bandwidth for non-essential
repetitive data.   Certainly, they all agreed that the absence
of a posting was good enough, rather than posing a form
saying "Did not observe".  That was a little much!  I'm quite
sure that the form coupled with the "Did not observe" submissions are 
the posts that set people complaining.  Up until then several people
had written about their observing runs the night before and the were quite
enjoyable.  I saw no one object to these.

Come on'...  post your observations.  Especially if you have a 
question about you've seen.  Just keep the length reasonable
and "content/form" ratio high.

Keywords: CCD silicon cleaning

I have a VLSI CCD chip which has gotten what looks like a blob of (food)
grease on the imaging surface. Needless to say I would like to get rid 
of the blob in order to use the chip. All I have been able to gather
about the cleaning of CCD devices is "don't" and "use a soft brush or
dry gas". In my case I think that neither a soft brush or a dry gas
would work. I think I need some sort of solvent to lift off or dissolve
the grease.

My question is: What solvent should I use to clean this delicate
structure and how should it be used or applied? I was thinking of Freon
or ether, but I really don't know. What solvents are used during the
manufacture of such devices?

Please reply by e-mail to gadallah@wu2.wl.aecl.ca (Larry Gadallah)

I will summarize and post to the appropriate group if there is a large

An excellent discussion of all of this is Tippler and Barrow, _The
Cosmological Anthropic Principle_. They have two Anthropic Principles:

Weak: The physical laws of the Universe must be such that carbon based
intelligence can evolve.

Strong: The physical laws of the Universe can only be such that carbon
based intelligence can evolve.

The WAP is obviously true, since we exist. The SAP would be true if
every logically consistent possible set of physical laws leads to
conditions suitable for the evolution of carbon based intelligence.

These principles have actual applications. For instance, why is the
Universe so big? Because evolution takes a long time, which implies a
large size for the Universe. A smaller one would have collapsed before
we evolved. The book has a better example I can't recall, in which a
nuclear anti-resonance was predicted based on the WAP because
otherwise there wouldn't be any oxygen. In addition, Tippler and
Barrow show that carbon based life actually depends on some very
subtle particle physics. So, one could argue that (for instance) the
fine structure constant is 1/137 because if it weren't, we wouldn't
exist.

Dominique,
  Thanks for the info, I hyper 2415 in 92%N, 8%H2, at 50 C, 3 PSIG, for 90
hours.  This runs the base fog density to something around .6.  I am putting
a list of the various films and hyper information together.  This project
has been ongoing for the last few years.  Once I finish, I will post here.
 
  How does the HG-400 look?  Any color shift?  Also do you see any problems
by leaving it in the cassette?  I have stayed away from hypering film while
it is in the cassette due to worry about uneven hypering.

I hope you can help me with a question.  A conference was
apparently held earlier this year in Spain, the topic at
least including helioseismology and solar physics. 

RSVP at the address below if you know who I can contact for
preprints, proceedings, or just a chat.

Thanks.
