A couple of weeks ago Ed and I noticed that Lacrosse 2 had made a change in its mean motion and was running 30 seconds early. Ian Porter has now made a couple of observations and I have awakened from my slumber and come up with a "guess" than the new mean motion is about 0.000800 greater than the previous value. Here is the old orbit: Lacrosse 2 1 21147U 91017 A 97180.96193788 0.00000030 00000-0 51481-5 0 09 2 21147 67.9810 111.4389 0008000 302.4702 57.5298 14.68595839 05 It is currently running about 80 seconds earlier than predictions made with this elset. Here is my guess for the new orbit: Lacrosse 2 1 21147U 91017 A 97210.38271202 .00000030 00000-0 51386-5 0 01 2 21147 67.9810 33.8600 0008000 271.5273 88.4727 14.68677604 08 Mike McCants
