    Last night there was a favorable pass of the Cosmos 2407 rocket
    (2004-028B, NCat 28381) and I observed that it was tumbling
    with a period of 11.7 seconds.  The last observation in the
    PPAS was in January - Leo reported that it was steady.
    
    Spacecom tles indicate an anomalous decrease in mean motion from
    13.77657 revs/day to 13.77651 revs/day over the period Mar. 17 to
    Mar. 25 and then an increase in mean motion to 13.77700 from
    Mar. 25 to Apr. 4.  There has been a very small decrease in mean
    motion since then, so there is a chance that the tumble period
    may still be decreasing.
    
    PPAS report:
    04- 28 B 06-04-14 02:00      MM  105.4 0.3   9 11.7   +4.5->8
