    On 051104 I think I have recovered 05512A, a near GSO object discovered
    in January 2005, and as far as I know not seen since late January.
    
    It was about 16 minutes later than the nominal prediction (nominal assumed
    NDOT2=0). It was flashing mag 5 or 6 every 27.15 sec, similar to January.
    
    The obs were
    (OTWG format see  http://www.satobs.org/position/UKformat.html)
    0551201211505110421291428  040  13015470  -0369   015 5             +50   
    02715F
    0551201211505110421350733  040  13020023  -0348   003 5
    0551201211505110421353459  040  13020067  -0346   004 5
    0551201211505110421381736  040  13020344  -0327   007 5
    0551201211505110421384450  040  13020381  -0327   005 5
    Observations 2 and 3 may have a 27sec time error.
    
    If I adjust NDOT2 to -.00000014 as in the elements below then I
    get a good match to the obs.
    
    1 90029U 05512A   05023.88729000 -.00000014  00000-0  00000+0 0    05
    2 90029  13.5000  15.2200 0005000 355.6600   4.3357   .98956700    07
    
    On 051104 it was flashing at 2128 UT (maybe earlier) at RA=0154 Dec=-3.7
    and was still flashing at 2141 UT RA=0206 Dec=-3.2.
    From the January obs the part of the sky where it flashes will not
    change much from night to night.
    It is currently well placed for Europe, Africa and west Asia, drifting 
    westwards
    about 4 degrees per day.
    On 051105 it will be at the RA/Dec above from 2146 to 2158,
    On 051106 it will be at the RA/Dec above from 2204 to 2215.
