MASTER-Kislovodsk robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) was pointed to the IceCube Alert 200410.97 (trigger No 24635982,16h 05m 03.84s , +11d 35m 06.0s, R=0.53) errorbox 20 sec after notice time and 73 sec after trigger time at 2020-04-10 23:21:08 UT, with upper limit up to 18.1 mag. The observations began at zenith distance = 33 deg. The sun altitude is -30.9 deg.
MASTER-Tavrida robotic telescope located in Russia (Lomonosov MSU, SAI Crimea astronomical station) was pointed to the IceCube Alert 200410.97 errorbox 38 sec after notice time and 90 sec after trigger time at 2020-04-10 23:21:26 UT, with upper limit up to 17.6 mag. The observations began at zenith distance = 36 deg. The sun altitude is -33.2 deg.
The galactic latitude b = 42 deg., longitude l = 24 deg.
