Аннотация:MASTER Global robotic net (MASTER-Net:http://observ.pereplet.ru Lipunov et al.,2010, Advances in Astronomy,2010,30L) automatically started (Lipunov et al. GCN 29544) Swift GRB 200222B (J.Gropp et al. GCN 29545, Ttrigger=22:37:26 UT) optical observations at MASTER-Kislovodsk at 2021-02-22 22:38:07UT (41s after trigger time in clouds), at MASTER-SAAO at 2021-02-22 22:42:03UT (GCN 29544). MASTER auto-detection system found MASTER OT J101825.41-145554.9, also detected by Swift (GCN 29545), and observed by BOOTES-1 (GCN 29546), LCO (29547), GOTO(29548), Liverpool Telescope (GCN 29549), NEXT (29551), VLT (GCN 29551) This OT was also observed by MASTER-IAC. The reduction of MASTER wide field and very wide field cameras images will be continued. This message may be cited.
