    Cosmos 2410 made its first manoeuvre a few hours ago, and it was typical of a
    Kobal't spacecraft: both perigee and apogee were raised, the argument of perigee
    was significantly decreased, and mean motion decreased to nearly 16.0 rev/d.
    Here are USSTRATCOM's before and after elsets:
                                                                165 X 318
    1 28396U 04038A   04275.49421296  .00889643  58249-5  21430-3 0   465
    2 28396  67.1502 220.1024 0115511  88.7479  59.3561 16.13805118  1092
    
                                                                218 X 336
    1 28396U 04038A   04275.73097671  .00158117  56608-5  18429-3 0   475
    2 28396  67.1583 219.3084 0088601  62.0401  17.5717 16.00857559  1132
    
    Based upon the above elsets, the pre and post manoeuvre orbits nearly
    intersected on 2004 Oct 01 at 15:32:46 UTC, 298 km above 37.4 S, 43.0 W, which
    was the approximate time and location of the manoeuvre.
