Integral GRB221010.89: 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 Integral GRB221010.89 (trigger No 10049,19h 34m 59.74s , +21d 55m 25.3s, R=0.0513333) errorbox 8596 sec after notice time and 8604 sec after trigger time at 2022-10-10 23:51:51 UT, with upper limit up to 18.0 mag. Observations started at twilight. The observations began at zenith distance = 55 deg. The sun altitude is -15.4 deg. The galactic latitude b = 0 deg., longitude l = 58 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2116623 We obtain a following upper limits.
