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) was pointed to the Swift GRB 250114A ( N. J. Klingler et al., GCN 38927) errorbox 18 sec after notice time and 63 sec after trigger time at 2025-01-14 07:34:22 UT, with upper limit up to 18.2 mag. The observations began at zenith distance = 18 deg. The sun altitude is -23.6 deg.
The galactic latitude b = 41 deg., longitude l = 270 deg.
Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2742671
We obtain a following upper limits.
Tmid-T0 | Site |Filt.| Expt. | Limit| Comment _________|_____________________|_____|_______|______|________
68 | MASTER-OAFA | C | 10 | 18.2 | Filter C is a clear (unfiltred) band.
The observation and reduction will continue. The message may be cited.
