    The last two nights I was able to observe Raduga 16 (85-070A, 15946)
    with a flash period of 56 seconds.  This was roughly 4:30 to 5:00 
    UTC.  Either it quits earlier each night or there was a phase shift
    Sunday PM and I gave up too soon.  But I was distracted by a very 
    slow moving object with a flash period of 7.5 seconds, maxima +7 at
    brightest.  It turned out to be Intelsat 501 Rk (81-050B, 12497) at
    a range of 9,600 km (6,000 miles).
    
    There's a report on sci.astro.satellites.visual-observe of the new
    Zenit (04-021B, 28353) flashing twice per second.
    
    Congratulations to the Spaceship One team!
