    The launch of Express 3A has produced two new decayers - its Proton
    rocket and platform. SpaceCom has posted decay notices for both, but
    I'll refrain from posting my SatEvo predictions for these until more
    elsets appear. Even so, I have updated my Decay Watch page
               http://www.wingar.demon.co.uk/satevo/dkwatch/
    with SpaceCom's predictions for these, plus my new prediction for Cosmos
    1077:
    
    #11268 = 79- 12 A = Cosmos 1077
    
    Current decay estimates:
       SpaceCom: Jun 26 18:56 +-2d         7.4 N   168.6 W
       SatEvo:   Jun 26 09:10 +-11h
    
    The latest elset...
    Cosmos 1077      5.0  1.5  0.0  5.4 v   13       211 x 198 km
    1 11268U 79012A   00176.40428241  .02605698 -94346-6  87011-3 0  6307
    2 11268  81.1604 214.1652 0009806 230.4744 330.6863 16.25669288176150
    ...shows this running 10 sec early against yesterday's prediction.

    #26379 = 00- 31 B = Express 3A Proton r
    
    Decay estimate:
       SpaceCom: Jun 26 05:31 +-1d        42.5 N    53.3 E
    
    Latest elset:
    Express 3A Proton r                              189 x 186 km
    1 26379U 00031B   00176.45615318  .02451766  12185-4  43086-3 0    63
    2 26379  51.6224 286.5406 0002509 308.6614 142.6117 16.31991201    76
    
    This enters eclipse while southbound near 50 deg S at ~17:30 local time.
    Eclipse exit occurs northbound near 37 deg N at ~03:30 local time. I
    hope to post predictions on my Decay Watch later today.
