Russell pointed out the magnitude ratio I posted was not quite right.
I calculate it as closer to 2.511886.
Here's a chart I made up showing relative brightness between any magnitude
difference
from 0.05 to 5.
Magnitude difference

0.05 1.047
0.1 1.096
0.2 1.202
0.3 1.318
0.4 1.445
0.5 1.584

For those who may have missed it, there is a vote now going on regarding
setting
up a new newsgroup about satellite observing. Will everyone please vote.
To vote, please obtain an official ballot (called a 'CFV') from one of
these
newsgroups:
news.announce.newgroups, news.groups, sci.astro, sci.astro.amateur,
sci.astro.planetarium, sci.space.policy or sci.space.shuttle
or, you can request a ballot by e-mail from
David Bostwick <bostwick@cas.chemistry.gatech.edu> and ask for the
sci.astro.satellites.visual-observe ballot.

We need to buy a muzzle for this guy ;)
As I've said before, campaigning for YES votes or NO votes can be used
against you if there is a protest. And since the newsgroup admin types
aren't exactly friendly to our proposal, I think we should be cautious not
to give them any ammunition. So our get-out-and-vote messages should be
neutral just to be safe.
I think it would be good if all three of you made up your own 'please vote'
messages for SeeSat-L so people can see that it's more than just me behind
this. Please include this in your messages:

I now have my e-mail list of amateur astronomers up to 200. I'm sending off
polite requests to them to please vote and I include the pointer stuff
above. I just started my 'underground' effort and I've already received
e-mails from 3 folks who promised YES votes...
c ya, Jim
