MASTER II robotic telescope (MASTER-Net: http://observ.pereplet.ru) located
near Kislovdsk was pointed to the Trigger 506913: Swift J1922.7-1716
(Barthelmy et al., GCN Circ 12522) 28 s after notice time and 98 sec after
Trigger time.
Unfortunately our first 10s exposure set in two polarizations are saturated
by evening sky light.
The preliminary photometry of the first unsaturated images gives:
UT T-T_trig mag
2011-11-03 14:55:24 2385s 17.4 +-0.3
Observations and data reduction are continuated.
