- Аннотация: MASTER-OAFA robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Argentina (OAFA observatory of San Juan National University) was pointed to the IC190221A (The IceCube Collaboration GCN 23918) 17 sec after notice time (47 sec after trigger time) at 2019-02-21 08:26:26 UT. The 5-sigma upper limit ~19 mag (180s exposition), we have 9 expositions. Also we have 4 images of the part of IC error-box in time ntervall 2019-02-21 08:01:49-08:14:20UT (11 minutes befor neutrino alert) during Fermi trigger inspection . The full analysys of ICECUBE error-box (RA: 268.81 [-1.8,+1.2], Dec: -17.04 [-0.5,+1.3] ) will be continued. The error box center galactic latitude b = 3.5 deg., longitude l = 11.7deg. The observations started when error-box altitude was 33deg. The sun altitude is -23.0 deg. The moon (96 % bright part) was 43 deg. above the horizon. The distance between moon and object was 91 The message may be cited.
