- Аннотация: MASTER-SAAO robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in South Africa (South African Astronomical Observatory) was pointed to the IceCube Alert 210322.11 (trigger No 19489408,05h 42m 01.68s , -44d 43m 19.2s, R=0.65) errorbox 36421 sec after notice time and 54330 sec after trigger time at 2021-03-22 17:39:39 UT, with upper limit up to 20.0 mag. Observations started at twilight. The observations began at zenith distance = 20 deg. The sun altitude is -11.9 deg. The galactic latitude b = -30 deg., longitude l = 251 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1573442 We obtain a following upper limits.
