Fermi trigger No 700976129: 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 GRB230320.15 (trigger No 700976129,18h 11m 00.00s , -46d 29m 24.0s, R=9.79) errorbox 244 sec after notice time and 276 sec after trigger time at 2023-03-20 03:40:00 UT, with upper limit up to 18.4 mag. Observations started at twilight. The observations began at zenith distance = 22 deg. The sun altitude is -13.8 deg. The galactic latitude b = -13 deg., longitude l = 347 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2205183 We obtain a following upper limits.
