    Hello everybody,
    
    I've seen several dozen satellites while observing Perseids on Aug
    10/11, 11/12 and 12/13.  Most of them were identified before or after
    observations but I failed to ID two flashers using SkyMap 6.5 and fresh
    Mike McCants' alldat.tle.
    
    Observation date: August 11/12, 2002
    Location: Vlasovo (90km north from Moscow)
    Lat, Long, Elev: 56o40'N, 37o52'E, 131 m
    Moscow Summer Time = UT+0400
    
    1. Unknown satellite in SSE-NNW direction flared to -2..-3m in Pegasus
    at 1:17 MSK Aug. 12 (21:17 UT Aug. 11), faded to +4.5m in Cassiopea and
    then suddenly flared again to -2m in UMa at 1:20.  Due to watch failure
    no precise timing was possible (had to use pager instead).  No exact
    position in my notes made the search yet more difficult.  Is there any
    hope to ID this one using such a crude description?
    
    2. -2m flare at 2:56 over alpha UMa was identified next morning as UME 1
    (8709, 76019A).
    
    3. Unknown flasher was spotted at 3:38 on ENE near epsilon Aurigae
    heading towards Perseus and Pleiades.  At 3:39-3:40 its path has almost
    crossed with a  brighter (2.5-3m) satellite.  The latter was moving
    faster with elevation still rising (appr. at 2:30 o'clock direction)
    while flasher was moving rather horizontally or a little bit downwards.
    One of two sats was IRS-1A, the other could have been Kosmos-1275 debris
    81053EJ.  Is any of them known to be tumbling?
    
    Sorry for not sending this request before - lots of work here lately.
    
    Several other sats were seen worth mentioning.
    Aug. 10/11: (observing from another location west from Moscow) USA-160
    and USA-160C at 0:50 through Sagitta and Delphinus; -7m Iridium 63 flare
    in Pegasus at 2:29;
    Aug. 11/12: -8m Iridium 66 flare in Pegasus at 2:23;
    Aug. 12/13 : -7m Iridium 18 flare in Perseus at 23:20 simultaneously
    with two (!) Perseid meteors.
    
    Best regards,
    
    Denis in Moscow
