MASTER II robotic telescope (MASTER-Net: http://observ.pereplet.ru)
located in SAAO was pointed to the GRB171011A 34 sec after notice time
and 273 sec after trigger time at 2017-10-11 18:37:20 UT. On our first
(50s exposure) set we not found optical transient within SWIFT
error-box (ra=236.758 dec=-10.0703 r=0.1) brighter then 17.7.
The observations made on zenit distance = 80 degrees, galaxy latitude b =
33 degree.
The moon (59 % bright part) below the horizon (The altitude of the Moon is
-51 degree ).
The sun altitude is -23.4 degree.
The error box can be observed till sunrise at 2017-10-12 03:59:47.
