    Ralph,
    Your estimate for Resurs was probably correct. By my description of right, I
    meant east of Orions belt so I should think that was it.
    Is this sat known for tumbling?

    Assuming by "Resurs 01 R/B" you mean (23343, 94-74A) it should have passed
    5-10 degrees left (east) of Orion's belt so most likely that wasn't it.
    Given the time and described track there are two candidates: Iridium 7
    (24793, 97-20B) and Cosmos 389 (04813, 70-113A). But neither of these, to my
    knowledge, are flashers. Perhaps we have another tumbling Iridium.
    
    Another possibility: About 7 to 8 minutes later (1541 to 1542 UT), ETS-6
    (23230, 94-56A) would have been about 5 degrees west of Orion's belt, moving
    slowly from west to east. However, ETS-6 has a flash period much slower than
    what you observed.
