MASTER-Amur robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Blagoveshchensk State Pedagogical University) was pointed to the IceCube Alert 220509.76 (trigger No 14688828,22h 18m 35.04s , +04d 57m 10.8s, R=0.91) errorbox 70 sec after notice time and 144 sec after trigger time at 2022-05-09 18:21:28 UT, with upper limit up to 13.2 mag. Observations started at twilight. The observations began at zenith distance = 71 deg. The sun altitude is -12.4 deg.
The galactic latitude b = -41 deg., longitude l = 69 deg.
Real time updated cover map and OT discovered available here:
