    Hi All
    
    A study of radio data from the NOSS constellation has revealed no sign 
    of NOSS 3-1 since I started looking during my predicted pass of NOSS 3-1 
    at ~0443UTC on November 16 (prior to Alain's report of a missing 
    object.)  Visual obs have not been possible due to weather for may days 
    here.
    
    All the other NOSSs have showed up on time with one interesting anomaly, 
    NOSS 3-2 seems to be consistently running ~3min late when using these 
    elsets from Mike's Classified TLEs:
    
    NOSS 3-2 (A)
    1 28095U 03054A   11309.00606613 0.00000030  00000-0  52008-4 0    07
    2 28095  63.4300 141.0143 0123000 359.6503   0.3496 13.40763624    01
    NOSS 3-2 (C)
    1 28097U 03054C   11309.00614772 0.00000020  00000-0  34621-4 0    04
    2 28097  63.4300 141.1867 0125000 359.5789   0.4211 13.40763551    09
    
    The following links provide the earliest Doppler curve from NOSS 3-2 I 
    have recorded:

    And this image shows the expected time of closest approach for the pass:

    Would be interesting to see if visual observation confirms this.
