MASTER-Amur robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Blagoveshchensk State Pedagogical University) was pointed to the Integral GRB220514.52 (trigger No 206528,09h 50m 40.06s , +13d 08m 49.6s, R=0.025) errorbox  2090 sec after notice time and 7953 sec after trigger time at 2022-05-14 14:37:57 UT, with upper limit up to  14.6 mag. The observations began at zenith distance = 68 deg. The sun  altitude  is -20.5 deg. 

MASTER-SAAO robotic telescope  located in South Africa (South African Astronomical Observatory) was pointed to the Integral GRB220514.52 errorbox  9941 sec after notice time and 15804 sec after trigger time at 2022-05-14 16:48:48 UT, with upper limit up to  16.7 mag. Observations started at twilight.  The observations began at zenith distance = 45 deg. The sun  altitude  is -12.6 deg. 

The galactic latitude b = 46 deg., longitude l = 223 deg.
