Fermi trigger No 724921799: 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 GRB231222.30 (trigger No 724921799,10h 45m 43.20s , -35d 59m 24.0s, R=1.21) errorbox 48203 sec after notice time and 48249 sec after trigger time at 2023-12-22 20:34:04 UT, with upper limit up to 17.5 mag. The observations began at zenith distance = 78 deg. The sun altitude is -27.2 deg. The galactic latitude b = 20 deg., longitude l = 277 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2339970 We obtain a following upper limits.
