Fermi GRB 230215A: 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 GRB 230215A ( Fermi GBM team, GCN 33326) errorbox 14520 sec after notice time and 14555 sec after trigger time at 2023-02-15 18:43:53 UT, with upper limit up to 16.7 mag. Observations started at twilight. The observations began at zenith distance = 79 deg. The sun altitude is -15.6 deg. The galactic latitude b = -61 deg., longitude l = 80 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2199216 We obtain a following upper limits.
