    Note: This had been lost between January 15 and 23. Indeed, my latest 
    SatEvo decay list gave January 15 as a possible decay date even 
    though the elsets on that date indicated a mean motion of 2.66 revs/day. 
    It is difficult to arrive at a satisfactory orbital evolution given the
    recent elsets, one of which suggests that it had a perigee height 
    of -11 km.
