- Аннотация: MASTER-Amur robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, v.2010, 30L) located in Russia (Blagoveshchensk State Pedagogical University) was pointed to the GRB190211A (Marshall et al. GCN 23883) 8 sec after notice time (46 sec after trigger time) at 2019-02-11 16:55:30 UT. On our first (10s exposure) set there is no optical transient within SWIFT error-box (ra=196.675 dec=41.9658 r=0.05) with 16.4m (5-sigma) upper limit (NEXT-0.6, Xu et al. GCN 23884 with RA,Dec=13:06:38.47 +41:58:04.93). The galactic latitude b = 75 deg., longitude l = 110 deg. The observations started when error box altitude was 65 deg. The moon (38 % bright part) altitude was -14 deg. The sun altitude was -50.9 deg. MASTER-Tunka robotic telescope located in Russia (Applied Physics Institute, Irkutsk State University) was pointed to the GRB190211A 38 sec after notice time (76 sec after triggertime) at 2019-02-11 16:56:00 UT. On our first (10s exposure) set we didn't find optical transient within SWIFT error-box with 5-sigma upper limit 16.4m The observations started when error-box altitde was 50 deg. The sun altitude was -51.9 deg. The message may be cited.
