Swift GRB230628.93: Global MASTER-Net observations report
Abstract
MASTER-OAFA robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Argentina (OAFA observatory of San Juan National University) was pointed to the Swift GRB230628.93 (trigger No 1177054,11h 27m 21.84s , -11d 26m 49.2s, R=0.05) errorbox 4426 sec after notice time and 4457 sec after trigger time at 2023-06-28 23:40:27 UT, with upper limit up to 18.1 mag. The observations began at zenith distance = 35 deg. The sun altitude is -24.6 deg. The galactic latitude b = 46 deg., longitude l = 273 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2230049 We obtain a following upper limits.
