MASTER-Tunka robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Applied Physics Institute, Irkutsk State University) started inspect of the Fermi GRB240205.14 (trigger No 728796365,21h 04m 19.92s , +03d 49m 58.8s, R=28.77) errorbox 27489 sec after notice time and 27525 sec after trigger time at 2024-02-05 11:04:45 UT, with upper limit up to 19.0 mag. Observations started at twilight. The observations began at zenith distance = 58 deg. The sun altitude is -10.0 deg.
The galactic latitude b = -28 deg., longitude l = 54 deg.
Real time updated cover map and OT discovered available here:
