MASTER-Kislovodsk robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) was pointed to the Swift GRB 211129A ( J.D. Gropp et al., GCN 31136) errorbox  17290 sec after notice time and 17308 sec after trigger time at 2021-11-29 14:39:34 UT, with upper limit up to  16.0 mag. Observations started at twilight.  The observations began at zenith distance = 45 deg. The sun  altitude  is -11.1 deg. 

The galactic latitude b = 20 deg., longitude l = 59 deg.


Real time updated cover map and OT discovered available here:
