Next the non-obs:
Ed's new flasher - 90907.  For the past 2 days this object has passed through 
the Delphinus constellation (165az, 65el).  For my area, the visibility was 
above average.  This indicates (for me, anyway) that it is a binocular object 
only in a dark-sky area.   

Iridium 27 produced bright (1x) flashes at 01:06:56 and 01:07:01 UTC on 12 
September.
DMSP (10033) produced bright flashes at 01:47:28 and 01:48:42 UTC on 12 
September.
Okean Rk (aka SL-12 and 25861) is flashing less rapidly.  Quikscat Rk (25790) 
has been bright and flashing.   As the Okean Rk becomes less visible due to 
seasonal lighting changes, this one will be interesting to observe.   Also, 
the Abrixas Rk (25723) has been flashing at about the same period as the 
Okean Rk (about 2x per second).  It is typically not visible at 1x but is an 
easy binocular object.
