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) started inspect of the Fermi GRB220803.40 (trigger No 681212354,13h 27m 24.00s , -58d 58m 58.8s, R=4.47) errorbox  47833 sec after notice time and 47838 sec after trigger time at 2022-08-03 22:56:28 UT, with upper limit up to  17.9 mag. Observations started at twilight.  The observations began at zenith distance = 34 deg. The sun  altitude  is -12.1 deg. 

The galactic latitude b =  3 deg., longitude l = 308 deg.
