Hello Bjorn,

It seems that #23405 94-77B (Cosmos 2297 r) has the better chances to be
the one that I search for. I received other elsets that reveiled the
same conclusion but you confirmed what I finally concluded.

-I want to know also if the "r" that follows the sat name means the
Upper Stage of the rocket that launched the sat and what is the R/B that
follows other sat name.

-Also I want to know where to find the Allan Tomsson's el960630.tle that
you refer in your reply.

-And finally, I saw tonight (July 9 01:58 GMT approx.) what it seems to
be UME 1
(#8709 76-19A) according to SatSpy with 1 week old elset. I saw a
flashing period of about 2.5 sec +/- .5 but in a file from BWGS, it
tells that it was observed a 3.745 sec. period for that satellite. Was
it the wrong sat or is the period changed since the observation from the
93 observation (in the file). If somebody observed lately that satellite
with his flashing period, could you tell me and the others if I'm wrong
or not if somebody could try to observe it.

Many thanks!

P.S: I'm new in satellite observation and in astronomy, so I don't know
the stars and the constellations but I will try to learn!!!
