USA 116 is usually manoeuvred on its perigee pass about three hours = after the USA 129 manoeuvre. Its mean motion is adjusted to about 0.005 to 0.01 higher than USA = 129's, but the difference will be reduced to its negative counterpart in = a few months time, because of USA 116's lower drag. Around Nov.29.878 USA 129 went into its higher orbit: USA 129 334.879 after manoeuvre ? 1 24680E 96072A 334.87900000 .00036489 00000-0 52143-3 0 10 2 24680 97.8663 35.0543 0513323 159.0563 0.2544 14.74593739 -1275 USA 116 search orbit: USA 116 +13 m/s Manoeuvre? 1 70061E 95066A 00334.96860000 .00020235 00000-0 45899-3 0 22 2 70061 97.9527 83.7704 0458414 11.7970 359.8537 14.75449079 1082 However, on Nov.29 the time (and ground track longitude) separation from = USA 116 was larger (02:48) than usual, so it is possible USA 116 was = allowed to stay a day or two more in the low orbit, to let USA 129 = reduce this difference: USA 116 335.99 +13 m/s Manoeuvre? 1 70062E 95066A 00334.96240000 .00020235 00000-0 45899-3 0 22 2 70062 97.9527 83.7704 0458414 11.7970 359.8537 14.75449079 1082 Also, three weeks have passed, adding to the normal uncertainty, so here = is a later pass: USA 116 +13.5 manoeuvre? 1 70063E 95066A 00334.96860000 .00020235 00000-0 45899-3 0 22 2 70063 97.9527 83.7704 0459740 11.7966 359.8541 14.75141254 1089 However, I believe more in the early orbit, 70062 ( or a 14.757 MM = variant of 70061) From Dec.22 USA 116 may reach 11 degrees above the S horizon for Tony = Beresford, a week later for Greg Roberts. I wish them the best of luck ! Is any observer living further south?
