MASTER-OAFA robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Argentina (OAFA observatory of San Juan National University) was pointed to the Swift GRB191016.17 (trigger No 929744,02h 01m 11.040s , +24d 30m 03.60s, R=0.05) errorbox  381 sec after trigger time at 2019-10-16 04:15:22 UT, with upper limit up to  15.8 mag. The observations began at zenit distance = 57 deg. The sun  altitude  is -50.3 deg. 

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