- Аннотация: MASTER-OAFA and MASTER-IAC automatically pointed to GRB 180314A (Eleonora Troja et al. GCN 22532) with optical transient detection by MASTER auto-detection system. We confirm Swift, LT, NOT, REM, RATIR, SLKT, D50 GROND OT (GCN 22532, 22534, 22535, 22536, 22537, 22538, 22541) but observed before. MASTER-OAFA robotic telescope (MASTER-Net: http://observ.pereplet.ru) located in OAFA (Argentina,http://oafa.master.sai.msu.ru:49001/) was pointed to the GRB180325.08 38 sec after trigger time at 2018-03-25 01:53:40 UT. On our second (20s exposure) set robot automaticaly found 1 optical transient within SWIFT error-box (ra=157.429 dec=24.4389 r=0.05) brighter then 16.7 . T-Ttrig Date Time Expt. Ra Dec Mag -------|-------------------|-------|-----------------|---------------|------- 88 2018-03-25 01:54:31 20 ( 10h 29m 42.7s , +24d 27m 49.3s) 16 The 5-sigma upper limit has been about 17.3mag ==================================================================== The observations made on zenit distance = 58 degrees, galaxy latitude b = 59 degree. The moon (55 % bright part) is 25 degrees above the horizon. The distance between moon and object is 53 The sun altitude is -40.3 degree. The object can be observed till 2018-03-25 07:53:41 UT. MASTER-IAC robotic telescope (MASTER-Net: http://observ.pereplet.ru) located in IAC (Tenerife, Tejde Observatory) was pointed to the GRB180325.08 63 sec after trigger time at 2018-03-25 01:54:09 UT. On our second (20s exposure) set robot automaticaly found 1 optical transient within SWIFT error-box (ra=157.429 dec=24.4386 r=0.05) brighter then 17.0. T-Ttrig Date Time Expt.

The moon (55 % bright part) is 6 degrees above the horizon. The distance between moon and object is 53 The sun altitude is -58.3 degree. The object can be observed till 2018-03-25 06:24:39 with good limit.
