MASTER-Tavrida robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Lomonosov MSU, SAI Crimea astronomical station) started inspect of the IceCube Alert 200109.99 (11h 01m 03.91s , +14d 55m 43.7s, R=1.9429) errorbox 20 sec after notice time and 75 sec after trigger time at 2020-01-09 23:42:55 UT, with upper limit up to 16.1 mag. The observations began at zenith distance = 36 deg. The sun altitude is -58.1 deg.
MASTER-IAC robotic telescope located in Spain (IAC Teide Observatory) started inspect of the IceCube Alert 200109.99 errorbox 50 sec after notice time and 105 sec after trigger time at 2020-01-09 23:43:25 UT, with upper limit up to 17.0 mag. The observations began at zenith distance = 71 deg. The sun altitude is -69.6 deg.
The galactic latitude b = 62 deg., longitude l = 234 deg.
