    Pardon me if I'm behind the curve on this, but I guess the 
    discussion is about the umbral shadow.  Iridflar gives 
    predictions for penumbral Iridium flares.  I don't know if 
    I've seen one yet; I see such a prediction only rarely.  
    Could a satellite just skimming the inside edge of the 
    umbra still be illuminated as the Moon is during totality?
    
    Sunday PM was cloudy.
