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) started inspect of the Fermi GRB210615.89 (trigger No 645485036,07h 45m 04.80s , +12d 48m 00.0s, R=3.25) errorbox 84879 sec after notice time and 84906 sec after trigger time at 2021-06-16 20:58:58 UT, with upper limit up to 16.9 mag. Observations started at twilight. The observations began at zenith distance = 79 deg. The sun altitude is -11.8 deg.
The galactic latitude b = 18 deg., longitude l = 208 deg.
Real time updated cover map and OT discovered available here:
