Monday evening (8 June UTC), Mike McCants and I were able to 
observe both Milstar 3 and Milstar 3 Centaur in spite of 
significant cloud problems.  (Using handheld binoculars, I've 
now seen this Centaur three nights in a row [two of them with 
significant clouds] -- so it can't be too hard to find ... at
least from low-inclination locations!)  

Somewhat rough estimates for Quicksat intrinsic magnitudes 
are 1.5 to 2.0 for the Centaur and 2.0 for the payload (i.e., 
Molczan standard mag. estimates, 3.0 to 3.5 and 3.5).  Note 
that Milstar 3 Centaur was called 99010 for a short time.

Earlier, clouds did prevent observation of the NOSS/SDS 
object(s).
