IceCube Alert 200620.13: Global MASTER-Net observations report
Abstract
MASTER-SAAO robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in South Africa (South African Astronomical Observatory) was pointed to the IceCube Alert 200620.13 (trigger No 33533447,10h 48m 26.40s , +11d 57m 00.0s, R=0.68) errorbox 48529 sec after notice time and 48560 sec after trigger time at 2020-06-20 16:32:52 UT, with upper limit up to 18.4 mag. Observations started at twilight. The observations began at zenith distance = 46 deg. The sun altitude is -10.7 deg. The galactic latitude b = 58 deg., longitude l = 236 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1386385 We obtain a following upper limits.
