On Saturday, 5/27, I was watching object 17590 from a Quicksat prediction.
It was found as predicted.  Because of bright skys at our observing site,
we were also using binoculars.  Just past culmination, it began to get
brighter.  This brightness peaked, then decreased to the previous level
over about 45 seconds.  The predicted magnitude for that part of the
pass was 3.1 and becoming more faint.

From our viewing site, we estimated - 0.5 magnitude at the peak.  It
was very steady in it's brightness increase and decline.  There were no
minor flashes or other changes.  It was seen by a number of people at
the monthly star party for the Austin Astronomical Society.

Perhaps this is a large flat surface on the object??  The peak
was at 3:07:45 UTC on 5/28/95.
