    After a lull with no decay activity, we now have SpaceCom warnings for
    three decayers.
    
    #13964 = 83- 25 A = Molniya 1-57
    No further decay warning since SpaceCom's prediction this morning that
    this would decay late (UTC) today. I now predict this decay for Jan 23
    05:38 +-1.5d. Predicted elsets for every orbit over the next 24h are on
    my Decay Watch page - URL below.
    
    #7969 = 75- 56 B = Cosmos 744 rocket
    SpaceCom predicts that this will decay at Jan 22 16:45 +-2d. I compute
    Jan 22 21:18 +-20h. This enters eclipse near northern apex over the
    Arctic at about 16:00 local time and leaves eclipse near 49 deg S at
    about 22:00 local time, so it appears poorly placed for observation. The
    latest elset is:
    Cosmos 744 r     3.8  2.6  0.0  5.1 v 11.1       218 x 215 km
    1 07969U 75056B   00018.71681088  .01223383 -96525-6  60253-3 0   460
    2 07969  81.2294 259.0799 0002237  96.6617 263.4829 16.21020066353514
    
    #26044 = 99- 73 C = Cosmos 2368 Molniya platform
    The SpaceCom prediction is for this decay to occur at Jan 22 09:25 +-2d
    while I predict Jan 22 10:26 +-22h. This is well placed for northern
    observers. It enters eclipse at about 17:30 local time while southbound
    near 50 deg N. Eclipse exit occurs while southbound near 52 deg S at
    ~23:00 local time. the latest elset is:
    C 2368 Moln pl   3.0  0.0  0.0  5.5 d    9       323 x 173 km
    1 26044U 99073C   00018.65302791  .02216205  00000-0  84228-3 0   701
