MASTER-SAAO robotic telescope (MASTER-Net http://observ.pereplet.ru)
located in South Africa was pointed to the IceCube-161103 alert (Taboada
et al. GCN 20119, GCN 20120) at 2016-11-03 18:06:35 UT (32344 sec
after the trigger time 2016-11-03 09:07:31.12 UT).
MASTER auto-detection system doesn't find optical transient within
error-box brighter then unfiltered mlim=20.2 mag (the 5-sigma upper
limit), W=0.2B+0.8R calibrated by USNO-B1.
The observations made on 77 degrees zenit distance , galaxy latitude b =
-41 degree.
The moon (14 % bright part) is 26 degrees above the horizon. The distance
between moon and object is 137deg.
Observations started in twilight. The sun altitude is -13.1 degree.
The object can be observed till sunrise at 2016-11-04 03:35:05
MASTER-Kislovodsk robotic telescope was pointed to the IceCube-161103
alert 32819 sec after trigger time on 2016-11-03 18:14:30 UT.
MASTER auto-detection system doesn't found optical transient within
error-box brighter then 20.5m (unfiltered 5-sigma upper limit)
The observations made on zenit distance = 47 degrees, galaxy latitude b = -41 degree.
The moon (14 % bright part) below the horizon (The altitude of the Moon is -16 degree ).
The sun altitude is -46.1 degree.
The object can be observed till sunrise at 2016-11-04 03:47:43
