GRB 190531B: MASTER optical observation
Abstract
MASTER Global Robotic Net (Lipunov et al., 2010, Advances in Astronomy,vol.2010, 30L (http://observ.pereplet.ru) observed Fermi GRB 190531B (Ttrig=2019-05-31 20:10:12UT, GBM team GCN24695, Veres et al. GCN 24705; BALROG localization RA,Dec(2000) = 27.9(+/-0.8d) -40.8(+/-0.6) Kunzweiler et al. GCN 24696, GCN 24699, LAT localization RA,Dec= 24.37, -41.97 +-0.11d(90%) Axelsson et al. GCN24701, Swift XRT afterglow 01h 37m 11.09s -41d 57' 30.3" +-1.6 arcsec(90%) D'Avanzo et al. GCN24706, Evans et al. 24702 ) At alert time MASTER-SAAO: Error-Box_altitude=-15d, Sun_alt=-57d. MASTER-OAFA: Error-Box_altitude=+15d, Sun_alt=+15d MASTER-SAAO robotic telescope (located in South African Astronomical Observatory) was pointed to the GRB190531A 4934 sec after notice time and 20321 sec after trigger time at 2019-06-01 01:48:53 UT . Error-box_alt=21deg, sun_alt=-47deg. There is no OT at Swift XRT position with unfiltered mlim=20.6m MASTER-OAFA robotic telescope (located in Argentina) was pointed to the GRB190531A at 2019-06-01 08:55:19UT Error-box_alt=34deg, sun_alt=-32deg. There is no OT at Swift XRT position with unfiltered mlim=20.0m Reduction will be continued. The message may be cited.
