Fermi trigger No 658764238: 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) started inspect of the Fermi GRB211116.59 (trigger No 658764238,18h 24m 57.60s , -33d 36m 00.0s, R=2.01) errorbox 3364 sec after notice time and 14334 sec after trigger time at 2021-11-16 18:02:47 UT, with upper limit up to 15.9 mag. Observations started at twilight. The observations began at zenith distance = 59 deg. The sun altitude is -9.5 deg. The galactic latitude b = -10 deg., longitude l = 0 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1788210 We obtain a following upper limits.
