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 GRB191019.63 (trigger No 930285,22h 40m 09.120s , -17d 19m 58.80s, R=0.05) errorbox  610 sec after notice time and 685 sec after trigger time at 2019-10-19 15:23:59 UT, with upper limit up to  18.2 mag. Observations started at twilight.  The observations began at zenit distance = 70 deg. The sun  altitude  is -11.9 deg. 

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