I really appreciate all the help with my NOSS post. I might have spotted the
leading satellite had I been using my 3X night scope instead of my 7X binocs
but when I grabbed my night scope I forgot that the battery was out of it.

I saw another NOSS triad pass high overhead just after Midnight last night
(misplaced the details). I estimate it was at least two magnitudes dimmer
than what H-A predicted it should be. I tracked it with my night scope. It
is good to know that these NOSS satellites are usually going to be very
faint. It's also good to brace yourself and wait for them to pass by a
certain star to be assured of picking them up. I found that the pass after
midnight was moving so slowly and was so faint that it blended in with the
stars very well. I really had to concentrate so as not to lose track of it.
It reminded me of an old cartoon that's animation consisted of three tiny
dots on an acetate being pulled across a field of the same size tiny dots in
the background. The only way to pick it up is by its movement.

One other thing. If secret satellites are not supposed to be visible to
ground observers, could they camouflage them by painting them a dark color
or that complicate things?

Clear skies,

Yes, that's what you saw. Note that the trio is C, D, and E (instead of B).
C&D would have been very close to one another--nearly identical track and
only separated by 1-second (less than 0.5 in the sky). As they crossed
Lyra, E would have been about 3 higher and leading the other two by about

By your description, you must have been watching NOSS 2-1 (C) and (D). It is
sometimes hard to spot the outside one of the trio--in this case (E).
