- Аннотация: MASTER-OAFA robotic telescope (MASTER-Net: http://observ.pereplet.ru) located in Argentina was pointed to the GRB180404B (LaPorte et al. GCN 22590; Beardmore et al. GCN 22594) 27 sec after notice time and 45 sec after trigger time at 2018-04-04 02:12:29 UT. On our first 10s exposure image with unfiltered mlim=16.5 (5-sigma) we don't found optical transient within SWIFT error-box (ra=53.3792 dec=-50.195 r=0.05 LaPorte et al. GCN 22590) MASTER auto-detection system detected OT with RA,Dec=53.392900; -50.214903 and unfiltered m_OT = 18.4 (automatic reduction) on the summary image with 670s exposition started on 2018-04-04 02:12:29 (mlim=19.7) The message may be cited. ==================================================================== The observations started at zenit distance = 73 degrees, galaxy latitude b = -51 degree. The moon (86 % bright part) is 16 degrees above the horizon. The distance between moon and object is 115 The sun altitude was -46.8 degree.
