Fermi trigger No 726773850: Global MASTER-Net observations report
Abstract
MASTER-Tunka robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Applied Physics Institute, Irkutsk State University) started inspect of the Fermi GRB240112.73 (trigger No 726773850,17h 29m 57.60s , +29d 09m 00.0s, R=2.34) errorbox 60679 sec after notice time and 60712 sec after trigger time at 2024-01-13 10:29:17 UT, with upper limit up to 15.8 mag. Observations started at twilight. The observations began at zenith distance = 78 deg. The sun altitude is -9.8 deg. The galactic latitude b = 29 deg., longitude l = 53 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2354479 We obtain a following upper limits.
