Dmitry Chestnov posted: >Unknown distant satellite on polar orbit The range would seem to be about 20000 Km and the brightness of even a large object would be magnitude 9 or so. A brightening from 8.5 to 7 and back to 9.5 would seem to be a flare. I can fit these orbits to the observations: A 12 hour eccentric orbit with an unusual argument of perigee: 1 99991U 07193.07740740 0.00000000 00000-0 00000-0 0 09 2 99991 64.0000 305.7300 7000000 222.8000 137.2000 2.00600000 09 A 24 hour slightly eccentric orbit with the perigee at the point of observation. 1 99991U 07192.97552546 0.00000000 00000-0 00000-0 0 02 2 99991 69.1000 305.9100 2880000 350.0000 10.0000 1.00270000 00 An 8 hour orbit with the object near apogee: 1 99991U 07193.02542823 0.00000000 00000-0 00000-0 0 06 2 99991 64.0000 305.4300 6800000 211.8000 148.2000 3.00000000 08 A circular orbit: 1 99991U 07192.96118055 0.00000000 00000-0 00000-0 0 04 2 99991 68.5000 305.6700 0001000 222.8000 137.2000 1.88000000 04 A 4 day eccentric orbit: 1 99991U 07193.42423263 0.00000000 00000-0 00000-0 0 06 2 99991 68.5000 306.3200 7205000 312.8000 47.2000 0.25000000 00 I don't think any of these orbits is likely.
