MASTER-Amur robotic telescope  (Global MASTER-Net: 
http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, 
vol. 2010, 30L)  located in Russia (Blagoveshchensk State Pedagogical 
University) was pointed to the Swift GRB191115.48 (trigger No 937114,19h 
28m 42.96s , +38d 43m 48.0s, R=0.05) errorbox  43 sec after trigger time 
at 2019-11-15 11:27:04 UT, with upper limit up to  16.2 mag. The 
observations began at zenith distance = 44 deg. The sun  altitude  is 
-35.0 deg.

The galactic latitude b = 10 deg., longitude l = 72 deg.


Real time updated cover map and OT discovered available here:
