    Has anyone produced a light curve of non-flaring Iridia?  It occurs to me
    that when the body of the satellite is behind an antenna and the antenna
    happens to be tilted so as to show the observer space, the satellite might
    be very faint indeed, perhaps twinkling a bit as it reflects stars.
    Secondary question: has anyone tried to see any except solar and lunar
    Iridum flares/blinks?  Venus, Jupiter, Sirus, I-flares for example?
