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 Fermi GRB230903.44 (trigger No 715429986,19h 43m 52.80s , +58d 28m 12.0s, R=4.61) errorbox 6500 sec after notice time and 6534 sec after trigger time at 2023-09-03 12:21:55 UT, with upper limit up to 17.9 mag. The observations began at zenith distance = 7 deg. The sun altitude is -19.4 deg.
MASTER-Kislovodsk robotic telescope located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) started inspect of the Fermi GRB230903.44 errorbox 1 days 34646 sec after notice time and 1 days 34680 sec after trigger time at 2023-09-04 20:11:01 UT, with upper limit up to 18.0 mag. The observations began at zenith distance = 24 deg. The sun altitude is -38.1 deg.
The galactic latitude b = 16 deg., longitude l = 91 deg.
