Swift GRB231111.60: 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) was pointed to the Swift GRB231111.60 (trigger No 1195887,19h 20m 56.16s , +52d 26m 49.2s, R=0.05) errorbox 17 sec after notice time and 37 sec after trigger time at 2023-11-11 14:17:57 UT, with upper limit up to 19.4 mag. The observations began at zenith distance = 45 deg. The sun altitude is -44.8 deg. The galactic latitude b = 17 deg., longitude l = 84 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2301436 We obtain a following upper limits.
