As I saw Kosmos 1867(87-60A/18187) flashing yesterday, I was curious to find something back in recent elements of this object. The first 4 element-sets are showing a normal increase in Mean Motion but starting with the fifth element the increase of the MM is abnormal and is not in the line of expections we see with the other elements. Also note that the excentricity, beginning with the fifth element set is increasing while previous element sets are showing it is decreasing. Looking back in the PPAS I found no observations between 95343 and 96003. I expect that the acceleration must have happend somewhere between those two epochs. Does anyone have some observations especially between the two epochs mentionned above ? 87060_A 1 18187U 87060 A 95322.39790716 -.00000074 00000-0 10113-4 0 3568 2 18187 65.0047 312.3946 0012454 264.5032 95.4634 14.30092583436442 87060_A 1 18187U 87060 A 95335.19517727 -.00000073 00000-0 10580-4 0 3599 2 18187 65.0047 276.6391 0012382 265.4424 94.5245 14.30093051438275 87060_A 1 18187U 87060 A 95339.25114259 -.00000021 00000-0 -82204-5 0 3602 2 18187 65.0049 265.3068 0012333 266.2476 93.7200 14.30092878438857 87060_A 1 18187U 87060 A 95343.79661940 .00000034 00000-0 13186-4 0 3615 2 18187 65.0049 252.6079 0012281 267.1725 92.7947 14.30093189439503 87060_A 1 18187U 87060 A 96 03.97149092 .00000282 00000-0 14748-3 0 3684 2 18187 65.0037 182.2685 0013300 272.7740 87.1818 14.30105764443102 87060_A 1 18187U 87060 A 96 09.84560448 -.00000095 00000-0 21182-5 0 3706 2 18187 65.0047 165.8562 0013491 273.6553 86.2978 14.30104054443947 87060_A 1 18187U 87060 A 96 16.90852618 .00000017 00000-0 64916-5 0 3721 2 18187 65.0103 146.1246 0013709 274.3123 85.6416 14.30104292444950 I hope my observation of May 15 can quickly be confirmed.
