Swift GRB200215.61: 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 GRB200215.61 (trigger No 956639,02h 16m 29.28s , +12d 46m 51.6s, R=0.05) errorbox 20 sec after notice time and 40 sec after trigger time at 2020-02-15 14:40:12 UT, with upper limit up to 18.5 mag. The observations began at zenith distance = 70 deg. The sun altitude is -39.9 deg. The galactic latitude b = -45 deg., longitude l = 154 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1288551 We obtain a following upper limits.
