MASTER II robotic telescope (MASTER-Net: http://observ.pereplet.ru,
2x500mm,2 x 4 square degrees, 2 x 16Mpx Apogee CCD) located
at Kourovka Observatory has observed FERMI error box
GRB_RA: 313.740d {+20h 54m 58s} (J2000)
GRB_DEC: +32.350d {+32d 21' 00"} (J2000)
1.18 degres error box radius (Trigg Number 265206153)
starting after sunset (19:18:23.275, ~7 hours after GRB time) with 180s
exposure in R and V filters simultaniuosly at ~60 degrees zenit distance.
Robot do not detect OT with limit:
R>19.0 V>18.1
Our images cover 30% last 1 sigma error box (A. von Kienlin, GCN Circ
