    I had an unexpected break in the clouds, but managed only one, not so accurate
    point. It is about 0.3 s too early, and a about 0.05 deg off track:
    
    24680 96 072A   2701 F 20040326025812670 17 25 0233309+521734 27 S
    
    Site 2701: 43.68764 N, 79.39243 W, 230 m
    
    Fortunately, we already have quite a few points tonight from Europe, resulting
    in this elset:
    
    Observation arc 2004 Mar 23.81 - 25.85 UTC:
    
    USA 129         15.0  3.0  0.0  5.3 v
    1 24680U 96072A   04085.84099592  .00020840  00000-0  31730-3 0    01
    2 24680  98.0513 147.3009 0523544 163.2632 198.6614 14.71301670    03
    
    WRMS residuals = 0.019 deg
    
    Adding my point, weighted 50 percent, yields:
    
    Observation arc 2004 Mar 23.81 - 26.12 UTC:
    
    USA 129         15.0  3.0  0.0  5.3 v
    1 24680U 96072A   04086.11304449  .00021038  00000-0  32097-3 0    09
    2 24680  98.0515 147.5721 0523298 162.4024 199.6103 14.71313531    03
    
    WRMS residuals = 0.021 deg
    
    The latest manoeuvre occurred on 2004 Mar 23 at about 14:16 UTC, near apogee,
    over 9.7 S, 111.0 E. The perigee was raised about 5 km, and apparently the
    inclination was increased by about 0.09 deg. This was the second orbit
    maintenance manoeuvre in less than five days. The previous one occurred on 2004
    Mar 18 at about 17:43 UTC, near perigee, over 6.0 S, 123.0 W. The apogee was
    raised several km, and the inclination was increased by about 0.16 deg.
