- 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 Africa (South African Astronomical Observatory) was pointed to the GRB190114C (Gropp et al., GCN 23688) 24 sec after notice time and 45 sec after trigger time at 2019-01-14 20:57:48 UT. On our first (10s exposure in two polarization) set we found 1 optical transient (Tiurina et al., GCN 23690) within SWIFT error-box (ra=54.5042 dec=-26.9383 r=0.05) brighter than 17.3 . T-Tmid Date Time Expt. Ra Dec Mag --------|--------------------|-------|-----------------|-----------------|------- 50 2019-01-14 20:57:48 10 (03h 38m 01.15s , -26d 56m 47.07s) 11.10 The 5-sigma upper limit has been about 17.32mag Taking into account the observations on the MASTER-IAC at Canaries (Tiurina et al., GCN 23690) , we have a polarization photometry in 4-position angles! The message may be cited. ==================================================================== The galactic latitude b = -53 deg., longitude l = 222 deg. The observations made on zenit distance = 31 deg.The moon (56 % bright part) is 22 deg. above the horizon. The distance between moon and object is 41 The sun altitude is -30.6 deg. The object can be observed till 2019-01-15 01:56:12 . The 5-sigma upper limit has been about 16.54mag The message may be cited.
