I caught C* 2154 r = 21667 = 91- 59 A on the 10th UT with a period close 
to 15s, confirming Mike McCants' OBSs.  PPAS report should be forthcoming 
On page 68 of the March Sky&Telescope, Gerald Ouellette writes "23087 is 
usually obvious to the naked eye at 2nd magnitude or so".  Mike, what do 
you have for an absolute magnitude for 23087?  Rainer Kracht has 
identified this object as a Tselina-2 object at 850 km, and if I 
understand correctly, not a very bright one.  In my own experience, 
neither this object nor any of its sisters is even remotely 2nd magnitude. 
In my list of bright objects, available from the SeeSat-L archive, the 
historic brightest observation of them all is 3rd.  23087 has been such a 
poor performer that I have seldom seen it. 
If any of you are doing the math for the map on page 68, the latest elset 
from Goddard SFC OIG: 
C* 2278 
1 23087U 94023A   96040.30532652 +.00000223 +00000-0 +14683-3 0 02965

suggests that actually it will be over 3 minutes earlier than the map 
gives (near here for the pass described on line 9 of the table there).
