MASTER-OAFA robotic telescope (MASTER-Net: http://observ.pereplet.ru,
Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in
Argentina (OAFA observatory of San Juan National University) was pointed
to the INTEGRAL GRB181201A ((Mereghetti et
al., GCN #23469) 10 sec after notice time and 18 sec
after trigger time at 2018-12-01 02:40:30 UT. We discovered prompt growing (one mag per
minute) optical flash MASTER OT J211711.20-123751.4
(Podesta et al., GCN #23470; Gorbovskoy et al., Atel #12255) at RA,Dec =
21h 17m 11.20s -12d 37m 51.4s
Later we observed afterglow at MASTER-Kislovodsk (Lipunov et al., #23476),
MASTER-SAAO, MASTER-IAC and MASTER-OAFA against in B,V,R,I and Clear fiters.
Observations are continuated.
