    Dear Harro,
    
    We observed 22875 (93-067A Cosmos 2265) on 6 different passes
    from 1997 Jul 31 to 2002 Sep 08 and my notes have no indication
    of variation; with one exception, the apparent magnitude was
    4.4 - 5.6 and the [Mike McCants] quicksat "intrinsic"
    magnitudes were in the range 4.1 - 5.1 . Since our brightness
    estimates could be considered +/- 0.5 magnitudes, there seems
    no clear sign of variation. (The one exception was 1999 June
    26 when it appeared almost 2 magnitudes brighter than expected.)
    
    Clear and dark skies!
