MASTER-Kislovodsk robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) started inspect of the Fermi GRB 210615A ( Fermi GBM team, GCN 30239) errorbox 28 sec after notice time and 46 sec after trigger time at 2021-06-15 23:34:39 UT, with upper limit up to 18.9 mag. Observations started at twilight. The observations began at zenith distance = 31 deg. The sun altitude is -15.9 deg.
MASTER-IAC robotic telescope located in Spain (IAC Teide Observatory) started inspect of the Fermi GRB 210615A errorbox 147 sec after notice time and 166 sec after trigger time at 2021-06-15 23:36:39 UT, with upper limit up to 18.0 mag. The observations began at zenith distance = 70 deg. The sun altitude is -34.6 deg.
The galactic latitude b = 3 deg., longitude l = 110 deg.
