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 IceCube Alert 200614.53 (trigger No 72386329,01h 54m 48.96s , +31d 11m 34.8s, R=1.19) errorbox 17264 sec after notice time and 17313 sec after trigger time at 2020-06-14 17:29:54 UT, with upper limit up to 13.4 mag. Observations started at twilight. The observations began at zenith distance = 82 deg. The sun altitude is -15.5 deg.
The galactic latitude b = -29 deg., longitude l = 139 deg.
Real time updated cover map and OT discovered available here:
