OIG seems to be down at the moment, and these are no longer in "latest 5", and "historical query" takes many days? Working with Ir5 elsets 674, 675, 678, 680, 683 and Ir51 524, 525, 526, 528, 529, Rob's AllCola shows that the "old Ir5" was overtaken by Ir51 AND the "new Ir5" between 8/11/2001 1:12:49 and 8/11/2001 1:12:55, 32 km below. ----- from elset 675 : (from elset 674 1:12:10 - 1:13:51) 8/11/2001 1:12:54.41 50678 Iridium 5 32.4/ 32.4 14.0 -0.61 8/11/2001 1:12:50.05 50680 iridium 5 32.2/ 32.2 14.2 -3.04 8/11/2001 1:12:49.34 50683 Iridium 5 32.2/ 32.2 14.1 -3.45 8/11/2001 1:12:50.93 50526 iridium 51 32.1/ 32.1 14.2 -2.00 8/11/2001 1:12:51.63 50528 iridium 51 31.9/ 31.9 14.3 -4.42 8/11/2001 1:12:53.45 50529 Iridium 51 31.9/ 31.9 14.2 -5.46 The pre-encounter Ir51 TLEs give 00:44 and 01:14 674/675 are within 3 km of each other Aug.09-13. 678 is within 3 km from 680, 683, 526, 528, 529 up to 10 km from 525 but up to 140 km from 524 All other combinations show matching patterns. This confirms that elsets 678-683 and 526-529 refer to one object, but is not identical to ANY of the two objects before 01223.05. If the common object is Ir51, it maneouvred slightly Aug.07 noon ? ----- from elset 524: 8/ 7/2001 12:20:39.24 50525 Iridium 51 0.8/ 0.0 90.6 -2.34 8/ 7/2001 5:39:06.61 50526 iridium 51 0.2/ 0.2 104.2 -5.81 ----- and/or Aug.09 (from elset 525): 8/ 9/2001 15:57:33.27 50526 iridium 51 0.4/ 0.4 42.0 -3.38 ----------------------------------------------------------------- Unsubscribe from SeeSat-L by sending a message with 'unsubscribe' in the SUBJECT to SeeSat-L-request@lists.satellite.eu.org http://www2.satellite.eu.org/seesat/seesatindex.html
