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.
