GRB 231129C: MASTER OT detection
Abstract
MASTER Global robotic net (http://observ.pereplet.ru Lipunov et al.,2010,Advances in Astronomy,2010,30L) started GECAM-B (Ttrigger=2023-11-29 19:10:18.2, Tnotice_socket=2023-11-29 19:11:45.56 Zheng et al. GCN 35231) and Fermi very bright GRB 231129C (Ttrigger=2023-11-29 19:10:18.11, Tnotice_socket=2023-11-29 19:19:40.72 Sharma et al. GCN 35227, GCN 35238, also MAXI-GSC (GCN 35223), CALET (GCN 35228), AstroSat (GCN 35230)) 55 sec after notice time and 90 sec after trigger time at 2023-11-29 19:11:48 UT (Lipunov et al. GCN 35216) by MASTER-SAAO. There is OT source at R.A.,Dec(2000)=00:44:37.97 -81:59:48.75 +-4" with m_OT~17.6 at maximum (unfiltered) at first images with decay inside Swift XRT error-box (Evans et al. GCN 35225, Gropp et al. GCN 35234) Reduction will be continued.
