- 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) started inspect of the IceCube Alert 220304.74 (trigger No 4701751,03h 15m 19.20s , +04d 27m 50.4s, R=1.25) errorbox 399 sec after notice time and 452 sec after trigger time at 2022-03-04 17:51:44 UT, with upper limit up to 19.3 mag. Observations started at twilight. The observations began at zenith distance = 54 deg. The sun altitude is -9.4 deg. The galactic latitude b = -42 deg., longitude l = 177 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1902082 We obtain a following upper limits.
