Fermi GRB 240112B: 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 240112B ( Fermi GBM team, GCN 35521) errorbox 23429 sec after notice time and 23473 sec after trigger time at 2024-01-12 19:30:39 UT, with upper limit up to 19.2 mag. The observations began at zenith distance = 47 deg. The sun altitude is -18.7 deg. The galactic latitude b = -51 deg., longitude l = 306 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2354342 We obtain a following upper limits.
