    If the San Francisco Bay area has such a decay window, please let me know
    when and where to look!
    I am about to go mobile to Manteca for a graze that occurs at 5:45 AM, so
    haven't and will not have a chance to see if such a chance exists..

    We had a ROSAT pass only about 10-15 minutes after sunset here in southern 
    Arizona tonight.  I tried to observe it from Kitt Peak where it should have 
    passed at close to 60 degrees above the horizon.  The sky was very bright 
    with twilight, but I was hoping it might flare or maybe even be a contrail 
    with a ground track less than maybe 100km away.  I watched from more than 5 
    minutes before the predicted pass until more than 5 minutes after but did
    see anything.  I'm guessing the sky was too bright, though we were within
    decay window given the latest predictions....  I watched from UT 00:50-01:08
    and the middle of the pass should have been 00:59 or so.
