MASTER-OAFA robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Argentina (OAFA observatory of San Juan National University) started inspect of the Fermi GRB 250214A ( Fermi GBM team, GCN 39320) errorbox 560 sec after notice time and 594 sec after trigger time at 2025-02-14 05:42:01 UT, with upper limit up to 19.1 mag. The observations began at zenith distance = 30 deg. The sun altitude is -44.1 deg.
The galactic latitude b = -4 deg., longitude l = 259 deg.
Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2777807
We obtain a following upper limits.
