- Аннотация: MASTER-SAAO robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in South African Astronomical Observatory, was pointed to Swift Trigger 886157 (S. D. Barthelmy et al., GCN 23800; Barthelmy et al. ATel 12436; Ttrig=2019-01-28 01:22:25 UT) 23 sec after notice time (370 sec after trigger time) at 2019-01-28 01:28:35 UT. There is no new OT, connected with GRB, with mlim=19.4 (5-sigma upper limit) on first 70s-exposition image inside Swift BAT error-box. There is no OT inside Swift XRT position (Kennea et al. ATel 12445) on first MASTER images (started at 2019-01-28 01:28:35) with mlim=19.4 and at 2019-01-29 01:44:03UT on 2 MASTER-SAAO inspect images with unfiltered mlim=20.0 (5-sigma). The galactic latitude b = -2 deg., longitude l = 352 deg. Alert observations started at zenit distance = 72 deg. The moon (48 % bright part) was 41 deg. above the horizon. The distance between moon and object is 47 deg. The sun altitude was -25.6 deg. The message may be cited.
