Fermi trigger No 623846261: Global MASTER-Net observations report
Abstract
MASTER-Tunka robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Applied Physics Institute, Irkutsk State University) started inspect of the Fermi GRB201008.44 (trigger No 623846261,10h 41m 55.20s , +47d 39m 00.0s, R=3.33) errorbox 27862 sec after notice time and 27870 sec after trigger time at 2020-10-08 18:22:07 UT, with upper limit up to 15.8 mag. The observations began at zenith distance = 70 deg. The sun altitude is -41.6 deg. The galactic latitude b = 58 deg., longitude l = 165 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1458009 We obtain a following upper limits.
