GREAT!!!!     This shows that you are seeing a set of bright
flashes about the same time that I am.  Last night I elected
to stop observing after my set of flashes centered at about
2:32:55 UT.  Excellent agreement there.  By also seeing the
0235 UT set of flashes, you should eliminate a source of
frustration in analyzing the orientation (right Rob?).

This remains a significant difference in our obs.  I do have
equally bright (or close to it) flashes at 11.7 second intervals.
The 5.8 second set of flashes may have been observed two nights
ago but that is not certain.

I may be the guilty party.  However, last night I observed through
those clouds and had a good session. If you assume that the clouds
cut out the fainter flashes (11.7 sec interval), and that it was 
the same on both ends (no guarantee), then I was able to get a
reasonable center time for the bright flashes.

Rob Matson,

You will notice that I did not include all flash timings last night.
I am trying to provide essential info in a more compact manner that
still allows folks to analyze this satellite.  My question for you
is:   What information do you feel is relevant and how much detail
is wanted?
