- Аннотация: MASTER-OAGH robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Mexico (OAGH National Institute for Astrophysics, Optics and Electronics) was pointed to the IceCube Alert 220421.22 (trigger No 43687362,07h 37m 27.60s , +06d 02m 13.2s, R=0.74) errorbox 314 sec after notice time and 361 sec after trigger time at 2022-04-21 05:26:19 UT, with upper limit up to 17.8 mag. The observations began at zenith distance = 67 deg. The sun altitude is -39.6 deg. The galactic latitude b = 14 deg., longitude l = 213 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1949987 We obtain a following upper limits.
