- 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) started inspect of the Fermi GRB220725.24 (trigger No 680421061,16h 46m 26.40s , -42d 13m 12.0s, R=17.14) errorbox 445 sec after notice time and 486 sec after trigger time at 2022-07-25 05:59:02 UT, with upper limit up to 17.8 mag. The observations began at zenith distance = 68 deg. The sun altitude is -69.2 deg. The galactic latitude b = 1 deg., longitude l = 343 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2040348 We obtain a following upper limits.
