OIG has named 24958 (97058C) "Sputnik Jr" in their thirty.tle file, so
that confirms Vladimir Agapov's previous post. Anyone else think the Jr
(Junior) name is just a little *too* cute? In any case, I took all the
24958 elsets I could find, and using the epoch dates for each I think
I've produced a reasonably correct assessment of where Sputnik was in
relation to Mir over the past few days. According to the elsets,
Sputnik is now trailing Mir, and probably has trailed since launch.
This conclusion of mine is based solely on the elsets, not any visual
or radio observations.

The time given earlier by Vladimir for the Sputnik release was 11/3 at
approx. 04:05 UT. The earliest "Revolution 1" elset I could find was
dated about 14.5 hours after that, so obviously there are more actual
revolutions than listed above.
Here are the elsets I used, with dummy catalog numbers to make it easier
for me to do my comparisons.
