03790B continues toward decay, sometime in December or January. 03790B 0.0 0.0 0.0 3.5 v 1 90019U 03790B 04277.37325858 .00532341 00000-0 78477-3 0 06 2 90019 27.3066 310.3119 0777964 296.1803 56.0793 14.47087917 00 Arc 2004 Oct 01.39 - 03.40, WRMS residuals = 0.009 deg I a beginning to doubt that Lacrosse 4 manoeuvred lower. A longer observation arc is required to be certain, but I suspect that the lower altitude is due to a large increase in the rate of decay since about Sep 22 UTC. Here is my latest solution assuming normal rate of decay: 1 26473U 00047A 04277.40453288 .00000100 00000-0 18903-4 0 06 2 26473 67.9886 59.7982 0008016 120.5347 239.6571 14.64134973 00 Here is the high rate of decay solution: 1 26473U 00047A 04277.40453910 .00001761 00000-0 33401-3 0 01 2 26473 68.0041 59.8102 0005839 314.5072 45.5576 14.64138631 04 If additional observations from last night are posted, then I will revisit this analysis. If there has been a jump in the rate of decay, then it would have to be due to the spacecraft entering an attitude that increases its ballistic coefficient by about an order of magnitude.
