MASTER-SAAO robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in South Africa (South African Astronomical Observatory) started inspect of the Fermi GRB191221.80 (trigger No 598648473,02h 43m 19.20s , -43d 02m 24.0s, R=5.86) errorbox 22 sec after notice time and 66 sec after trigger time at 2019-12-21 19:15:35 UT, with upper limit up to 19.8 mag. Observations started at twilight. The observations began at zenith distance = 13 deg. The sun altitude is -16.6 deg.
MASTER-IAC robotic telescope located in Spain (IAC Teide Observatory) started inspect of the Fermi GRB191221.80 errorbox 54 sec after notice time and 99 sec after trigger time at 2019-12-21 19:16:07 UT, with upper limit up to 16.9 mag. Observations started at twilight. The observations began at zenith distance = 80 deg. The sun altitude is -13.9 deg.
The galactic latitude b = -62 deg., longitude l = 255 deg.
