Аннотация: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 GRB221013.04 (trigger No 10076,19h 34m 58.26s , +21d 52m 54.1s, R=0.0541667) errorbox 182 sec after notice time and 205 sec after trigger time at 2022-10-13 00:56:04 UT, with upper limit up to 18.2 mag. The observations began at zenith distance = 62 deg. The sun altitude is -27.6 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=2119782 We obtain a following upper limits.
