    Mike McCants was able to observe last night and confirmed
    that the twilight one that I saw Tuesday evening (local)
    was indeed TDF 2 (20705, 90-63A), a near-geosynch that's
    drifting westwards each night.  Except for the moonlight,
    its brightest flashes might have been visible one-power.
    It was visible in binoculars from about 2:45 to 3:35 
    last night, June 8 UTC.  That was about 20 to 25 minutes
    later than the previous night.  Flash period is about
    21.some seconds (PPAS reports are "still to be sent").
    
    Mike also observed my "UNID A", as did the observer in 
    Colorado, so more data on that one may be available soon.
    Since I first saw it on June 1 UTC, it's been tracking 
    along an imaginary line that could be drawn from phi
    Virginis (about 14:25, -2 [1950]) towards a little 
    triangle at about 14:59, -2.5.  It's been easily visible 
    in binoculars several minutes earlier and a little bit 
    farther west each night.  Last night (June 8 UTC) it was 
    first visible a little east of phi Vir.  It was visible
    from about 3:48 (binoculars) to after 4:01 (telescope).  
    It may still turn out that this is a known object....
    
    A California observer reported that GSTAR 1 (15677, 85-35A)
    was easily visible again, and Mike and I also observed it 
    last night.  I timed it from about 3:31 to 3:42, when it
    was about time to look for UNID A.  It's visible about 10
    minutes earlier each night; flash period 72.5 seconds.
    
    Observing location:  30.314N, 97.866W, 280m.
