Fermi trigger No 712390645: 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 GRB230730.26 (trigger No 712390645,13h 39m 00.00s , +32d 54m 00.0s, R=33.9) errorbox 1 days 29758 sec after notice time and 1 days 29791 sec after trigger time at 2023-07-31 14:33:51 UT, with upper limit up to 16.8 mag. Observations started at twilight. The observations began at zenith distance = 74 deg. The sun altitude is -12.4 deg. The galactic latitude b = 78 deg., longitude l = 63 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2247493 We obtain a following upper limits.
