Swift GRB230311.82: 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) was pointed to the Swift GRB230311.82 (trigger No 1159437,16h 33m 41.21s , -47d 38m 32.3s, R=0.05) errorbox 40 sec after notice time and 478 sec after trigger time at 2023-03-11 19:46:31 UT, with upper limit up to 16.2 mag. The observations began at zenith distance = 85 deg. The sun altitude is -33.9 deg. The galactic latitude b = -0 deg., longitude l = 337 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2203796 We obtain a following upper limits.
