Charles (and everyone else): You can query TruSat for them. https://www.trusat.org/object/41941 Here's a few to get you started. I don't know why it was variable in Feb, and not the other times. 41941 17 005B 7779 G 2020010112155798 17 25 1241610-301587 16 +156 10 41941 17 005B 7779 G 2020010112165798 17 25 1244766-294478 16 +157 10 41941 17 005B 7779 G 2020010112173302 17 25 1246549-292763 16 +150 10 41941 17 005B 7777 G 2020020204463401 17 25 1429333-083683 16 R+159 10 020000 41941 17 005B 7777 G 2020020204473401 17 25 1430567-082385 16 R+148 10 020000 41941 17 005B 7777 G 2020020204494098 17 25 1433203-075623 16 R+136 10 020000 41941 17 005B 7779 F 2020042310531802 17 25 1858880+172654 16 S+168 10 41941 17 005B 7779 F 2020042310541802 17 25 1859373+172547 16 S+168 10 41941 17 005B 7779 F 2020042310543604 17 25 1859537+172546 16 S+166 10 41941 17 005B 7779 F 2020042310553604 17 25 1900041+172444 16 S+174 10 41941 17 005B 7779 G 2020060205045302 17 25 1815815+155132 16 S+181 10 41941 17 005B 7779 G 2020060205055302 17 25 1816587+155094 16 S+182 10 41941 17 005B 7779 G 2020060205062599 17 25 1817045+155104 16 S+181 10 41941 17 005B 7779 G 2020060205072599 17 25 1817803+155074 16 S+181 10 Brad Young PE Visual: Oberwerk 8 x 40 Mariner binoculars Meade ETX-125 22" f/4.2 UC Obsession COSPAR 8336 =TULSA1 +36.139208,-95.983429 660ft, 201m COSPAR 8335 =TULSA2 +35.8311 -96.1411 1083ft, 330m Remote Imaging: MPC I89 COSPAR 7777 38.165653 -2.326735 5150ft, 1650m Nerpio, Spain MPC Q62 COSPAR 7778 -31.2733 149.0644 3400ft, 1122m Siding Spring, NSW, Australia MPC H06 COSPAR 7779 32.92 -105.528 7298ft, 2225m Mayhill, New Mexico USA MPC 323 COSPAR 7782 -32.008 116.135 984ft, 300m Perth, WA, Australia On Tuesday, June 30, 2020, 11:19:27 AM CDT, Charles Phillips via Seesat-l <seesat-l_at_satobs.org> wrote: All - One of the interesting things that you can see if you look at the TLEs for various high eccentricity objects is some odd behavior in apogee and perigee. Many high eccentricity objects, when their perigee gets down to the neighborhood of 500 km or so, show a near-sinusoidal variation in perigee while the apogee tends to show a steady decrease. We currently have one object in the list that has a low perigee - one object that does not have orbital parameters available from Space-Track - and it is the object with the lowest perigee. That is object 41941, an upper stage from a Japanese geo comm satellite. There appears to be little reason for the US to hide the orbital parameters for this object, probably it was classified a few years ago and might have been forgotten. There are other objects with similar orbits that were classified and now show in the Satellite Catalog (11720, 16591, etc). Anyway 41941 is kind of odd because the perigee appears to be steadily decreasing while the apogee is increasing. That is unusual. If anyone had any spare time - could they track 41941? I would like to have some more points to plot. I did mention the fact that it might have been overlooked to the CSpOC, hopefully they will realize that it is not in the Satellite Catalog and will declassify the TLE. Thanks.
