    As Alan Figer first noted:
    
    http://www.satobs.org/seesat/Nov-2011/0179.html
    
    ...one satellite of the NOSS 3-1 duo has gone AWOL....
    
    Above positions on the remaining object, best fit NOSS 3-1A (26905, 01-040A). So 
    it is the C component (26907, 01-040C) that has disappeared....
    
    Note: *very* marginal trail on the photograph. Conditions were not good (hazy 
    and unfavourable phase angle).
    
    Also obtained video, showing the A object very well when passing through Lyra 
    but no second object. I filmed from 1.5 minute before to 3.5 minutes after the pass.
