    Hi all,
    
    I just visually observed the main wrecks of both Iridium 33 and Kosmos 2251 with 
    the ETX-70 (7 cm F5 refractor).
    
    The Iridium 33 wreckage (24946, 97-051C) was easy to see and notably irregular 
    in brightness, with many short flashes (several per second, with a brighter one 
    approximately each second. This is an estimate: I did not time them). I observed 
    it as it passed close to Pollux near 19:55:10 UTC (11 March). At its brightest 
    it might have been +6. I did not observe the kind of bright flares as reporetd 
    by Simone yesterday.
    
    The Kosmos 2251 wreckage (22675, 93-036A) was much fainter, about +8 at its 
    brightest as it passed close to alpha Uma at 20:11:30 UTC. It too was irregular, 
    but its brightness variation seemed slightly slower than that of the Iridium 33 
    wreckage.
