Following is a personal analysis of these observations based
on predictions made with Satspy v3.0 ephemeris using SGP4 orbital
model and element sets from molczan.tle :
Intl ID Name Timing Off predicted Elset epoch
track
86017 A Mir complex Early 50.7 s 0.363° to the NW 99014.476
86046 B Cosmos 1758 r Early 1.0 s 0.144° to the W 99014.497
82079 A Cosmos 1400 Early 1.4 s 0.062° to the E 99013.703
71038 B Cosmos 409 r Late 0.6 s 0.006° to the W 99014.199
79090 B Cosmos 1141 r Early 0.4 s 0.030° to the E 99014.144
87027 B Cosmos 1833 r Early 0.2 s 0.110° to the W 99013.182
92093 B Cosmos 2227 r Late 1.9 s 0.028° to the E 99014.166
64004 B Echo 2 r Late 0.3 s 0.009° to the W 99014.206
89068 A Cosmos 2037 Early 0.2 s 0.036° to the W 99013.186
Time uncertainty : +/- 0.3 sec
Position uncertainty : 0.1 degree
Notes :
1- These are my first observations using my new 20x80 binoculars.
2- Cannot explain why Mir was so off time and track. My timing for this
one had an uncertainty of +/- 1.5 sec.
3- Also observed 98023 C, #25308, Globalstar 14 around 23:33 UTC but
didn't time it. It was around mag 7.
4- While I was observing Saturn, an unidentified sat crossed my field
of view in my binocs at around 1 degree to the east of the planet.
I later determined it was 83004 B, #13778, IRAS r observed at 00:42.
