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 GRB190324.95 (  3h 18m 18.24s , -47d 14m 20.40s, R=0.05) 2541 sec after trigger time at 2019-03-24 23:26:22 UT, with upper limit up to  17.5 mag. Observations started at twilight.  The observations began at zenit distance = 45 deg. The sun  altitude  is -10.4 deg. 

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

We obtain a following upper limits.
