The following USA 144 elset is a couple of days older than the one I posted
earlier today. It may be of interest to analysts and archivists.

Pierre comments that USA 144's high ndot/2, which averaged 0.00000116 rev/d^2
during 4 - 24 Sep, was caused by luni-solar perturbations and solar radiation
pressure.
Also, Lacrosse 2's high ndot/2, which averaged 0.00001051 rev/d^2 during 24
Aug - 21 Sep, was caused by drag, due to a period of high solar activity.
Likewise, Lacrosse 3, which ndot/2 averaged 0.00000851 rev/d^2 during 26 Aug -
25 Sep.
