Swift GRB210603.41: 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 GRB210603.41 (trigger No 1053220,15h 55m 16.56s , -54d 02m 45.6s, R=0.05) errorbox 40 sec after trigger time at 2021-06-03 09:46:26 UT, with upper limit up to 16.7 mag. The observations began at zenith distance = 66 deg. The sun altitude is -20.8 deg. The galactic latitude b = -1 deg., longitude l = 328 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1627464 We obtain a following upper limits.
