- Аннотация: MASTER Global Robotic Net started automatically IC181023A alert (from socket coordinates) observations 22 sec after notice time (MASTER-Tavrida) and continued 1 day later as IceCube-181023A (Blaufuss et al.GCN 23375,Pizzuto et al. GCN 23380) inspection at MASTER-Kislovodsk. MASTER-Tavrida robotic telescope (MASTER Net: Lipunov et.al. 2010, Advances in Astronomy, vol. 2010, 30L http://www.hindawi.com/journals/aa/2010/349171/), located in Lomonosov MSU, SAI Crimean astronomical station, was pointed automatically to the IC181023A error-box (taken from the socket) 22 sec after notice time and 66 sec after trigger time at 2018-10-23 16:38:38 UT. We observed this socket error-box with unfiltered mlim=18.3 and not found new OT, connected with EHE neutrino astrophysical source. The galactic latitude b = 7 deg., longitude l = 19 deg. The observations made on zenit distance = 68 deg. The sun altitude was -20.7 deg. The moon (99 % bright part) was 21 deg. above the horizon. The distance between moon and object was 109 deg. MASTER-Kislovodsk started IceCube-181023A (Blaufuss et al.GCN 23375 (RA:270.18 (-1.70,+2.00 deg); Dec: -8.57 (-1.30,+1.25 deg)) inspection with mlim=17.0 between clouds at 2018-10-24 15:31:39 UT The observations made on zenit distance = 63 deg. The moon (100 % bright part) was 11 deg. above the horizon. The distance between moon and object was 121 deg. The sun altitude was -15.2 deg. Observations and more accurate reduction will be continued. This message may be cited
