    The current elsets for the Iridiums show no evidence that any de-orbit
    manoeuvres have started. However, it appears that no Iridium elset has
    had a negative drag term (ndot2) since about March 22. I speculate that
    this is evidence that efforts to control the relative positions of the
    satellites have terminated. Can anyone "in the know" confirm this?
    
    Of course, the thing that determines whether flares occur as predicted
    is the attitude control of the Iridium, not its relative position in the
    constellation, and even if it drifts off-station it may still be under
    attitude control.
