As those of you who subscribe to the SPACEWARN mailing list (e-mail to 
majordomo@nssdc.gsfc.nasa.gov with body: subscribe swb-list) may already 
know, the bright part of my latest list of bright objects appeared 
yesterday in the draft version of SPACEWARN Bulletin Number 513, 
http://nssdc.gsfc.nasa.gov/spacewarn/spx513.html.  The list itself is 
http://nssdc.gsfc.nasa.gov/spacewarn/spx513-brightobjects.html, and is a 
supplement to the earlier list (which is available in 
http://nssdc.gsfc.nasa.gov/spacewarn/spx490-brightobjects.html).  The new 
supplement contains observations from the past 2 years. 
 
With the indulgence of Messrs. Clifford and De Pontieu, the full 
supplemental list will soon be available from the SeeSat-L archive and by 
FTP.  If you want to know what can be seen, the list represents a good 
source.  If you want fairly consistent performance in generating 
"predictions", the best source I know of is Mike McCants' catalog which is 
incorporated in QuickSat, available from the SeeSat-L archive.  People are 
always asking "Which satellites are easiest to see?  What's on your 
Top-10?".  The best simple answer I know to those questions is QuickSat 
with Ted Molczan's file as input. 
 
The bright part contains 141 objects; the full list will be over 240; the 
earlier full list was 385 (it's available from the archive). 
 
What am I talking about?  Here are the last 8 lines of the bright part of 
the list: 
 
Helios 1A r     23608  95- 33D  2 or 3   *0 
Sich 1          23657  95- 46A  4 
2321            23676  95- 52A  3 
2322            23704  95- 58A  4 
2322 r          23705  95- 58B  2 
2326            23748  95- 71A  1 or 1.5 
2327            23773  96-  4A  2 
NOSS 2-3 r             96- 29   0 
 
(This last is found in Ted Molczan's file as 96- 29B, although I don't 
know that there is yet any general agreement on the piece letters for the 
various pieces of that launch). 
 
Cheers.
