Integral GRB221012.68: 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 GRB221012.68 (trigger No 10061,19h 35m 00.19s , +21d 53m 48.0s, R=0.0541667) errorbox 25276 sec after notice time and 25284 sec after trigger time at 2022-10-12 23:27:10 UT, with upper limit up to 17.2 mag. Observations started at twilight. The observations began at zenith distance = 54 deg. The sun altitude is -10.0 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=2119309 We obtain a following upper limits.
