MASTER-IAC robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Spain (IAC Teide Observatory) was pointed to the Swift GRB191228.00 (trigger No 946476,00h 21m 21.36s , -08d 40m 12.0s, R=0.05) errorbox 146 sec after trigger time at 2019-12-28 00:03:46 UT, with upper limit up to 17.3 mag. The observations began at zenith distance = 82 deg. The sun altitude is -75.7 deg.
The galactic latitude b = -70 deg., longitude l = 102 deg.
Real time updated cover map and OT discovered available here:
