    Tubsat N is probably down, though the final notice from SpaceCom has yet 
    to appear. This is taken from my updated Decay Watch page:
    _____________________________________________________________________
    Object: #25389 = 98- 42 A = Tubsat N
    
    Decay predictions:
    Source   Prediction made    Predicted decay at      Latitude Longitude
                    UTC                UTC                  deg      deg

    Latest elset:
    Tubsat N         0.5  0.5  0.0  9.0 d 0.27       137 x 128 km
    1 25389U 98042A   02112.72053695  .21305737 -27307-7  16620-3 0  1662
    2 25389  78.8379 109.6476 0007143 152.2943 208.7109 16.52619024210179
    
    Note: This decay slipped very much later than I predicted but has
    probably already occurred. Indeed, the latest elset, above, may be
    the final one. I put the decay northbound to the W of the Bay of
    Biscay following the orbit for which the latest elset applies.
