MASTER II robotic telescope (MASTER-Net: http://observ.pereplet.ru)
located in Kislovodsk was pointed to the GRB150626B 216 sec after notice
time and 260 sec after trigger time at 2015-06-26 20:27:12 UT in two
polarizations, directly after automatic weather control system give permit
for observations. On our first (50s exposure) set we not found optical
transient within SWIFT error-box (McCauley et al. GCN 17966) brighter then
17.5.
The 5-sigma upper limit has been about 17.5 mag
MASTER-IAC pointed to the GRB150626B 46 sec after notice time and 90
sec after trigger time at 2015-06-26 2015-06-26 20:24:22 UT, but the
images overexposed due to eveninig sky (Sun alt -4 deg.).
The observations is continued.
