Fermi trigger No 683152759: Global MASTER-Net observations report
Abstract
MASTER-Amur robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Blagoveshchensk State Pedagogical University) started inspect of the Fermi GRB220825.86 (trigger No 683152759,08h 46m 12.00s , +29d 52m 01.2s, R=32.47) errorbox 72583 sec after notice time and 72614 sec after trigger time at 2022-08-26 16:49:29 UT, with upper limit up to 18.9 mag. The observations began at zenith distance = 63 deg. The sun altitude is -27.3 deg. The galactic latitude b = 37 deg., longitude l = 195 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2067619 We obtain a following upper limits.
