MAXI GRB230408.82: Global MASTER-Net observations report
Abstract
MASTER-Amur robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Blagoveshchensk State Pedagogical University) started inspect of the MAXI GRB230408.82 (trigger No 2674032,02h 41m 06.24s , +61d 18m 57.6s, R=1) errorbox 25600 sec after notice time and 56967 sec after trigger time at 2023-04-09 11:24:48 UT, with upper limit up to 17.2 mag. Observations started at twilight. The observations began at zenith distance = 49 deg. The sun altitude is -11.6 deg. The galactic latitude b = 2 deg., longitude l = 136 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2209442 We obtain a following upper limits.
