- 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 220627.74 (trigger No 22443736,11h 01m 41.52s , +05d 00m 00.0s, R=0.51) errorbox 47 sec after notice time and 88 sec after trigger time at 2022-06-27 17:53:22 UT, with upper limit up to 19.8 mag. The observations began at zenith distance = 53 deg. The sun altitude is -26.7 deg. The galactic latitude b = 56 deg., longitude l = 249 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2016799 We obtain a following upper limits.
