    While watching for a flash from Raduga 21, suddenly I realized 
    that there was a extra magnitude 4 star in my field of view!
    As I recorded more Raduga 21 flashes, the extra star moved 
    slowly east and north and in a couple of minutes faded away.
    Cosmos 2395 (02-060C, 27619) is a good match.  I first noticed 
    it a degree or two east of mu Virginis (+3.9 mag), at about 
    RA 14:48, Dec -4.4 (2000).  It disappeared at about RA 14:53, 
    Dec -2.8.  At 4:57 UTC (about the time it disappeared), the 
    Sun was at RA 2:26:20.2, Dec +14:29.4.
