- 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 220624.68 (trigger No 7637140,14h 57m 35.28s , +40d 41m 09.6s, R=0.51) errorbox 19838 sec after notice time and 19885 sec after trigger time at 2022-06-24 21:44:41 UT, with upper limit up to 18.4 mag. The observations began at zenith distance = 80 deg. The sun altitude is -74.9 deg. The galactic latitude b = 60 deg., longitude l = 68 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2014640 We obtain a following upper limits.
