Hi all,

 Had an interesting UnId Observation this evening.  After collecting
flash data on Ir 14? & Ir 11 tum (veni, flashi, exiti) and observing
what I thought was NOSS 0 (D) (turned out to be Cosmos 2211 Rk) I
spotted, through  binoculars, at first what I thought was an aircraft
strobe light.  But, it
was invisible to naked eye so I followed it.  It flashed at maybe mag
5.5 to 7 distinct in binoculars but again invisible to the naked eye and
invisible in between flashes (0.2secs).

Its period was about 3 flashes per second, very unusual. Aircraft
strobes are usually 1 per second and one can see red and green running
lights.  I passed it off as probably a high flying aircraft.  But the
abrupt end of the obsrvation suggested a satellite that passed into
shadow. Later, I checked passes for the evening and found that this
"aircraft" matched, near perfectly, EGP 16908, (86061A)'s trajectory.
The observation abruptly ended at the time EGP passed into shadow.  I
timed obs at

Kochab
 00:43:03 - at Kochab  RA145142.3 Dec740802
Below Polaris
 00:44:48 (3d below polaris) approx. RA090029 Dec871015
End of Obs
 00:46:55 lost it to Shadow between A & G Cam 041549 68.0

 Has anyone else observed this object and noted the unusual flashing?
