Luc Fontaine <lfontain@quebectel.com> asked :
It seems that #23405 94-77B (Cosmos 2297 r) has the better chances to be
the one that I search for.....
 -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.


Yes - I use r,R,rk,Rk unsystematically to designate rocket bodies.
NASA OIG uses R/B;
R/B(1) and R/B(2) (or R/B(PKM) or R/B(AUX MOTOR)
when more than one rocket stage is in orbit.
I prefer r and r2 in those cases.


el960630.tle is my modified file name after expanding el960630.Z
into el960630. Allen Thomsson's files are available on www, or
anonymously at ftp://kilroy.jpl.nasa.gov/pub/space/elements/satelem/

The latest file (now el960710.Z) is also stored as newelem.Z.
In ftp://kilroy.jpl.nasa.gov/pub/space/elements/molczan/ you can
find the shorter Ted Molczan csYYMMDD.Z files (and newmolc.Z)

An mirror of ftp://kilroy.jpl.nasa.gov/pub/space/elements/
is ftp://seds.lpl.arizona.edu/pub/sat/

In a directory above, you'll find the gzip utility to expand the
files, and a description. If you request the files via a ftp mail
server, you can omit the .Z part, and get them transmitted
expanded.

For 76-19A you may have measured a half flash period, as
indicated by 95-04-02 and 95-05-04 observations below.

The old flash period file you have read (end of Molczan cs96mmdd file?)
is superseded by tables in the 'Flash' magazines
