    I studied flashes from this object some years ago providing also predictions 
    for that time.
    Interesting to know that it may be still rotating with a similar period.
    Some comments are still available at the old site:

    >I observed last night by chance a nice flashing satellite from about 22h05.5 
    to 22h06.0 UTC using binoculars. The satellite was quite bright, exhibiting 
    quick variations in the range of mag 4.8 to 7 . I didn't attempt to estimate 
    its period, because it got eclipsed soon after culmination, while I was busy to 
    complete an accurate position measurement.
    >Maybe, if any, the period is less than 10 seconds.
    >Using Calsky, I identified the satellite as object 33777 (1997-51 Q) Iridium 
    33 Q debris. This object is not listed in the PPAS, although a few other 
    Iridium 33 debris already are.
