    No wonder Mike and I failed to see Raduga 33!  We looked too 
    late.  Robert Fenske wrote:

    The Austin culmination of that much better elset was 2:00:27.  
    I had it at 2:02:22, with one-minute uncertainty, using this 
    elset:
    
    Raduga 33
    1 23794U 96010A   04124.79412371  .50827871  14928-4  27717-2 0  5006

    Later Mike began searching for 97-68B (25035).  It turned up 
    in his field of view after about 45 minutes.  This was very 
    good luck!  In spite of it being within 30 degrees and less 
    of the Moon, from at least 3:00-3:07, south of Arcturus, it 
    was not hard to see in my 8x42, and it did some significantly 
    brighter flashes than its usual maxima.
    
    Without binoculars Gravity Probe B was visible for a long 
    time and then did one fairly bright flash in the NW.
    
    Without binoculars I watched Fleetsatcom 4 Centaur Rk 
    (12069) for four minutes -- a very nice pass.  I watched 
    four final flashes with magnification.  PPAS:
    
    80- 87 B 04-05-04 02:40:26   EC  323.5 0.5  23 14.07  +1.5->inv
    
    Shi Jian 4 Rk (94-010C, 22997), a Long March, was very bright.  
    It was easy to see without binoculars even fairly near the 
    Moon, and its range over there was 1500-1600 km.  It seems 
    its Quicksat intrinsic magnitude may be +1.0 rather than the 
    +1.5 that I've had for it.
    
    BCRC: 30.315N, 97.866W, 280m.
