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 GRB240215.65 (trigger No 729703985,09h 15m 43.20s , -07d 10m 48.0s, R=11.87) errorbox 274 sec after notice time and 311 sec after trigger time at 2024-02-15 15:38:11 UT, with upper limit up to 19.4 mag. The observations began at zenith distance = 60 deg. The sun altitude is -46.5 deg.
The galactic latitude b = 28 deg., longitude l = 239 deg.
Real time updated cover map and OT discovered available here:
