	Last night centered around 9:34 pm (Jun 04 2:34 UTC) as I was
watching HST go by I spied a satellite moving parallel with HST and with
nearly identical apparent motion.  This other satellite was slowly
flashing from about +4/invisible (+4 was about my limiting mag) to about
+3; the period was on the order of 20-30 seconds.  I did a search with
Mike McCant's alldat.tle and didn't find a suitable candidate.  I saw this
satellite as it travelled east from it's culmination at 50-60 deg el at
150-170 az to somewhat due east as it vanished into the glare of San
Antonio's light (no dark sight here!).  Can anyone help me with
identifying this sat?  I observed from 29.4695N 98.657583W, 213.0m alt.
