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 GRB181213.54 (Evens et al. GCN 
23525) 81 sec after trigger time at 2018-12-13 12:58:59 UT, 
with upper limit up to  17.3 mag. The observations began at zenit distance 
= 51 deg. The sun  altitude  is -50.9 deg.

We find bright OT  at a position
  16h 33m 04.88s , +78d 29m 48.15s
with magnitude is about 14.9


The galactic latitude b = -60 deg., longitude l = 98 deg.
