MASTER-OAGH robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Mexico (OAGH National Institute for Astrophysics, Optics and Electronics) started inspect of the Fermi GRB 220330A ( Fermi GBM team, GCN 31806) errorbox 37 sec after notice time and 66 sec after trigger time at 2022-03-30 12:29:15 UT, with upper limit up to 17.1 mag. Observations started at twilight. The observations began at zenith distance = 47 deg. The sun altitude is -9.6 deg.
MASTER-Amur robotic telescope located in Russia (Blagoveshchensk State Pedagogical University) started inspect of the Fermi GRB 220330A errorbox 51 sec after notice time and 80 sec after trigger time at 2022-03-30 12:29:29 UT, with upper limit up to 17.9 mag. The observations began at zenith distance = 67 deg. The sun altitude is -23.1 deg.
The galactic latitude b = 8 deg., longitude l = 103 deg.
