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 GRB200219.32 (trigger No 957271,22h 50m 34.56s , -59d 06m 28.8s, R=0.05) errorbox 74 sec after trigger time at 2020-02-19 07:38:03 UT, with upper limit up to 16.5 mag. The observations began at zenith distance = 87 deg. The sun altitude is -31.2 deg.
The galactic latitude b = -52 deg., longitude l = 328 deg.
Real time updated cover map and OT discovered available here:
