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) started inspect of the IceCube Alert 231103.39 (trigger No 8773328,06h 57m 00.48s , +46d 34m 51.6s, R=1.08) errorbox 25857 sec after notice time and 25909 sec after trigger time at 2023-11-03 16:29:24 UT, with upper limit up to 18.0 mag. The observations began at zenith distance = 31 deg. The sun altitude is -51.8 deg.
The galactic latitude b = 21 deg., longitude l = 170 deg.
Real time updated cover map and OT discovered available here:
