    Why does the entire Iridium constellation show up as
    being modified?  Anyone have a clue? 
    
    ------------------------
    Obs from Last night...
    
    Cosmos 1206 flared to about a +1 mag high in the NNW at
    about 22:51 UTC 4 January.  Unfortunately I lost it
    when I went to retrieve my stopwatch and picked it up
    low in the SSW for the final 30 seconds of the pass. I
    did not observe and brihgtness change (~4.5 steady).
    
    PCSat (26931, 01043C)was +6 mag as it passed between 
    alpha and delta Andromeda, high in the west at 00:23:40
    UTC 5 January.  It suddenly faded to inv.  Since the
    payload is a cube, like Sunsat, I would think that you
    get either a great deal  of reflected light or none at
    all(ie. no gradual dimming).
    
    Iridium 13 flared to the predicted -2 mag at 22:47:33
    UTC 4 January.
