I can't tell if your interesting message is a response to mine (in the
appendix). It sounds like not, but I think you should have gotten it by
now. 22709 = 93-44A = C* 2258 and its friends are explicitly mentioned
there in this context. Or maybe there is no mail delivery/reading problem
and you just believe in ignoring others' observations and just charging
ahead. That's fine, too.

23343 = 94-74B = Resurs 1-3 r is indeed quite bright. I've seen it only
once, I think, so I didn't mention it in my message. There is a
refinement of suitability for general public participation that deserves
expression and further study. Mir and the shuttles are always bright, but
can be 3 to 5 mags fainter than expected on rare occasions. Perhaps dim
passes of the Lacrosses are a bit rarer. So far the only two I know about
are one of each, one by Mike and one by me. I fear less confident
observers may have had similar experiences but were reluctant to say so
for fear of exposing incompetence. (Cf. my comments on OBS philosophy
the other day). Noting a different perspective, you have previously
reported seeing bright flashes from one of the radar satellites. The
EORSATs like C* 2258 are very reliable, but not so reliable as Mir, the
shuttles and the Lacrosses. I've never been disappointed when an EORSAT
reached a high altitude. 21148 = 91-17B = Lacrosse 2 r is a nasty case,
because when it is good it is very, very good (2nd to Mir in brightness
among the regulars), but it often disappoints. I wonder if people at
different latitudes have different experiences to report.

22566 = 93-16B = C* 2237 r was steady the last time I looked at it, also;
but let me say to the general reader that it is good to be a bit cautious
about concluding from a single OBS that it now has a very long period.
These Zenits specifically, and satellites generally, often exhibit no
brightness variation during a large portion of a pass, while flashing
during the remainder of the pass. Or no flashing on a pass, followed by
flashing on a subsequent pass. I don't want to argue about C* 2237 r
specifically, because it has had a long and lengthening period now for
some months.
