- Аннотация: MASTER Global Robotic Net (http://observ.pereplet.ru, Lipunov et al., 2010,Advances in Astronomy, vol. 2010, 30L) started IceCube-190730A (Stein et al. GCN #25225) alert observations (Lipunov et al. GCN #25231) 28s and 56s after notice time at MASTER-Tavrida and MASTER-IAC. MASTER-Tavrida robotic telescope was pointed to the IceCube Alert 190730.87 ( 15h 07m 19.25s , +10d 30m 28.08s, R=0.7552) errorbox 28 sec after notice time (62 sec after trigger time) at 2019-07-30 20:51:43 UT, and observed it with upper limit 18 mag. MASTER-IAC robotic telescope pointed 56 sec after notice time (89 sec after trigger time) at 2019-07-30 20:52:11 UT, with upper limit up to 20 mag. For the FSRQ PKS 1502+106, suggested by Taboada et al. ATel #12967 as possible candidate to source of event and also analyzed by AGILE (Lucarelli et al. ATEL #12967), MASTER automatic preliminary archive and current photometry is the following: Date_Time_UT(Tstart) m_OT(unfiltered) 2015-07-04 00:12:08.4 16.0 2016-09-11 20:21:40.1 17.7 2018-01-05 06:10:59.8 15.9 2018-09-09 20:38:24.9 18.0 2019-04-15 00:06:40.5 18.1 2019-07-30 20:54:54.2 18.0
