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

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.
