Swift GRB200716C: Global MASTER-Net OT detection
Abstract
MASTER-IAC robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Spain (IAC Teide Observatory) was pointed to the GRB200716C (Ukwatta et al, GCN 28124) 55 sec after notice time and 79 sec after trigger time at 2020-07-16 22:59:00 UT. On our 5-th (50s exposure) set , obtained 243 sec after tigger time at 2020-07-16 23:01:45 UT, we found an optical transient within Swift error-box (ra=196.012 dec=29.6292 r=0.05) brighter.
