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 Swift GRB 220930A ( S. B. Cenko et al., GCN 32603) errorbox 11539 sec after notice time and 11568 sec after trigger time at 2022-09-30 14:24:40 UT, with upper limit up to 19.3 mag. The observations began at zenith distance = 69 deg. The sun altitude is -41.3 deg.
The galactic latitude b = -25 deg., longitude l = 181 deg.
Real time updated cover map and OT discovered available here:
