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 GRB221204.45 (trigger No 1143281,19h 58m 06.86s , +35d 00m 18.4s, R=0.05) errorbox 201 sec after notice time and 282 sec after trigger time at 2022-12-04 10:49:47 UT, with upper limit up to 15.4 mag. The observations began at zenith distance = 47 deg. The sun altitude is -31.0 deg.
The galactic latitude b = 3 deg., longitude l = 71 deg.
Real time updated cover map and OT discovered available here:
