MASTER-OAFA robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Argentina (OAFA observatory of San Juan National University) started inspect of the IceCube Alert 200914.00 (trigger No 12345,03h 24m 26.40s , +38d 06m 36.0s, R=5) errorbox 29612 sec after trigger time at 2020-09-14 08:13:32 UT, with upper limit up to 19.5 mag. The observations began at zenith distance = 67 deg. The sun altitude is -30.7 deg.
MASTER-Tavrida robotic telescope located in Russia (Lomonosov MSU, SAI Crimea astronomical station) started inspect of the IceCube Alert 200914.00 errorbox 68324 sec after trigger time at 2020-09-14 18:58:44 UT, with upper limit up to 19.6 mag. The observations began at zenith distance = 71 deg. The sun altitude is -30.9 deg.
The galactic latitude b = -15 deg., longitude l = 154 deg.
