Leo Barhorst noted that USA 276 has maneuvered. >42689 17 022A was imaged some 61 sec late on 3 day old TLE. Here are are pre-maneuver and post-maneuver elsets: 1 42689U 17022A 19176.91595239 0.00000000 00000-0 00000-0 0 01 2 42689 50.0027 165.8380 0014198 139.3071 220.7258 15.57984077 02 1 42689U 17022A 19179.93089930 0.00000000 00000-0 00000-0 0 02 2 42689 49.9990 150.1274 0013361 145.5264 214.5674 15.57709079 01 Leo's observations on June 25 at 22:22 UT are a good fit to both the previous elset and the new elset. So the small change in mean motion must have occurred about that time.
