Ed Light has reported a possible observation of USA 193, which I have confirmed: http://satobs.org/seesat/Feb-2008/0288.html 29651 06 057A 8840 P 20080216233501000 28 35 0639400-251000 18 +048 05 Lakewood, NJ, USA Site 8840, N 40.1075, W 074.2312, +24 m (80 ft) It was surprisingly close to the prediction of my high-drag elset of Feb 11, 0.65 s late, and within 0.05 deg of the track. 1 29651U 06057A 08042.43411818 .00214910 00000-0 31472-3 0 05 2 29651 58.4821 69.5983 0009338 66.1500 294.0578 16.04437931 07 I had expected the rate of decay to decrease, so had offered the following low-drag version; however, the object was 79.6 early and within 0.14 deg of the predicted track. 1 70000U 08042.43411819 .00170715 00000-0 25000-3 0 06 2 70000 58.4821 69.5983 0009338 66.1500 294.0578 16.04437931 01 Mike McCants also expected the rate of decay to decrease, and produced an elset similar to my low-drag version, shown below. The object was 61.3 s early, and within 0.63 deg of this elset. 1 29651U 06057A 08042.43405801 0.00185000 00000-0 27300-3 0 02 2 29651 58.5097 69.5541 0000897 125.0164 234.9836 16.04407073 09 I will post updated elements later this evening; in the meantime, observers who run their own predictions are advised to use the first of the above elsets. Mike's elset is the one in use by Heavens-Above, so until he produces an update and it finds it way to H-A, observers should expect the object to be at least 1 min early, and a bit off-track.
