Swift GRB201209.24: 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 GRB201209.24 (trigger No 1011980,01h 32m 25.44s , -01d 45m 46.8s, R=0.05) errorbox 29 sec after notice time and 51 sec after trigger time at 2020-12-09 05:45:44 UT, with upper limit up to 16.8 mag. The observations began at zenith distance = 75 deg. The sun altitude is -33.0 deg. The galactic latitude b = -62 deg., longitude l = 147 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1499038 We obtain a following upper limits.
