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 GRB191019.67 (trigger No 930285,22h 40m 05.760s , -17d 19m 44.40s, R=0.001) errorbox  3218 sec after notice time and 38 sec after trigger time at 2019-10-19 16:07:27 UT, with upper limit up to  18.9 mag. The observations began at zenit distance = 65 deg. The sun  altitude  is -19.8 deg. 

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