    I have updated my Decay Watch page at
            http://www.wingar.demon.co.uk/satevo/dkwatch/
    with updated predictions for the following. To make it a little easier
    to run your own predictions for these, I have collected the most recent
    elsets together in a single block at the end.
    
    
    #603 = 63- 22 B = Transit 5A3 Scout X-3 r
    
    I had hesitated to include this in my Decay Watch list because it has a
    relatively low Radar Cross Section of 0.61 m^2. However, SpaceCom has
    posted a decay warning for May 17 10:59 +-2d at 59.6 N, 11.9 W. My own
    calculations give May 17 08:59 +-22h. This enters eclipse near the South
    Pole and leaves eclipse near latitude 52 deg N at 22:00 local time while
    northbound.

    #10135 = 77- 61 B = Cosmos 925 r
    
    SpaceCom has joined the club with a prediction of decay at May 17 10:06
    +-2d at 0.0 S, 167.6 W. My current estimate is May 16 22:39 +-19h.
             _________________________________________
    
    #26085 = 00-  8 E = Globalstar 63 Delta 2 r
    
    SpaceCom has not moved from its prediction of decay at May 14 14:43 +-1d
    near 17.4 S, 39.0 W. My new estimate is May 15 07:23 +-9h at 11.0 S,
    139.8 W.
             _________________________________________
    
    #26114 = 00- 17 B = IMAGE Delta 2 r
    
    SpaceCom estimates decay at May 17 03:37 +-2d near 28.4 S, 92.8 W. I
    predict it for May 16 23:11 +-19h.
