Fermi trigger No 649390368: Global MASTER-Net observations report
Abstract
MASTER-IAC robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Spain (IAC Teide Observatory) started inspect of the Fermi GRB210731.09 (trigger No 649390368,02h 23m 52.80s , +22d 58m 48.0s, R=3.07) errorbox 80 sec after trigger time at 2021-07-31 02:14:03 UT, with upper limit up to 16.6 mag. The observations began at zenith distance = 62 deg. The sun altitude is -41.1 deg. The galactic latitude b = -35 deg., longitude l = 150 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1676367 We obtain a following upper limits.
