Just to add another data point:

I also observed the NOSS 2-2 cluster on 1996 08 11 at 02:45 UTC and have 
a photograph of the pass.  The three trails passing through Lyra show 
clearly on the negative.  I'll make a print over the weekend and post it 
somewhere if anyone is interested.  I observed the same cluster again at 
1996 08 14  02:23 UTC and again on 1996 08 15 01:40.  The pass on the 
11th was the brightest with all three at about 3.5 magnitude.

By chance, the Cosmos 2090 RB (90  70G , 20741) was also in Lyra with the 
cluster last night in the same field of my 10 x 50's as the two trailers 
but the leader didn't quite fit.  On lower power, there would have been 
four satellites in the same field.

The MOS 1A satellite (87  18A,  17527) is getting interesting if rather 
confusing.  Last evening, 1996 08 15, I watched it go from almost 
invisible in 10 x 50 to easy naked eye (between 1 and 2 magnitude) to 
totally invisible and back to and easy binocular object.  However, I can 
see no pattern in the variation.  I have just modified my logging program 
to log individual flashes so maybe that will help.
