Fermi trigger No 653079281: Global MASTER-Net observations report
Abstract
MASTER-Tavrida robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Lomonosov MSU, SAI Crimea astronomical station) started inspect of the Fermi GRB210911.79 (trigger No 653079281,20h 47m 33.60s , +10d 07m 12.0s, R=11.51) errorbox 737 sec after notice time and 905 sec after trigger time at 2021-09-11 19:09:41 UT, with upper limit up to 18.7 mag. The observations began at zenith distance = 33 deg. The sun altitude is -31.1 deg. The galactic latitude b = -21 deg., longitude l = 57 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1717843 We obtain a following upper limits.
