Sergienko Blagoveschensk Educational State University (BSPU) Global MASTER Robotic Net started new follow up optical observations of high energy (> 1Gev) neutrino from Baksan Neutrino Observatory Alerts (Petkov et al., Physics of Particles and Nuclei, 2015,Vol. 46, pp. 201-204.). MASTER-Tunka robotic telescope (MASTER-Net: Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L http://observ.pereplet.ru) located near Baykal Lake (Russia) started Baksan Neutrino Observatory BNO181021.79 ( RA_2000=124.3,+08.3, error-box=03deg, TriggerTime=2018-10-21 19:09:43UT, NoticeTime=19:50:20.18 UT) alert observations at 2018-10-21 19:50:49 UT (20 sec after notice time, 2466 sec after trigger time). The 5-sigma upper limit on our 540s images is 19.2 mag. Observations started, when Object_Altitude: 28.56 deg Sun_Altitude: -35.34 deg Moon_Altitude: 4.43 deg, Dist. to Moon: 128.694199 deg, Lunar disk: 0.91 Gal. latitude: 23.34deg, Gal. longitude: 215.67deg MASTER-Tavrida robotic telescope, located in Lomonosov MSU, SAI Crimea astronomical station, started BNO181021.79 alert inspection at 2018-10-21 23:54:02UT (17059 sec after trigger time) and observed till 2018-10-22 00:21:59UT. The 5-sigma upper limit on our 540s images is 19.0. Observations started, when Object_Altitude: 25.90 deg Sun_Altitude: -43.89 deg Moon_Altitude:13.64 deg, Dist. to Moon: 126.65 deg, Lunar disk: 0.92 Gal. latitude: 23.34deg, Gal. longitude: 215.67deg MASTER-SAAO robotic telescope, located in South African Astronomical Observatory, started BNO181021.79 alert inspection at 2018-10-22 01:50:11UT (20528 sec after trigger time). and observed it till 2018-10-22 03:00:55UT . The 5-sigma upper limit on our 540s images is 20.0. Observations started, when Object_Altitude: 30.8 deg Sun_Altitude: -23.59 deg Moon_Altitude: 10.92 deg, Dist. to Moon: 125.65 deg, Lunar disk: 0.92 Gal. latitude: 23.34deg, Gal. longitude: 215.67deg There are two QSOs inside neutrino error box. First of them has RA,DEC = 08 10 26.42 +10 10 40.99 in 0.421" with z=2.50589 (unfiltered MASTER magnitude m = 17.2 ). But there is no significant variability of its brightness since 2011-11-26 20:43:35.857UT in MASTER-Tunka database. Second one has coordinates 08 15 29.47 +09 54 40.7 with Z=1.7 and rmag=20.04 . The message may be cited.
