We observed the field of GRB 260114A (Eyles-Ferris et al., GCN 43396;
Fermi GBM team, GCN 43395; Bissaldi et al., GCN 43400) with the
AZT-33IK 1.5m telescope of the Mondy observatory starting on
2026-01-14 (UT) 12:17:27 in R filter. Within the Swift/XRT error
circle (Eyles-Ferris et al., GCN 43396) we detect the optical
counterpart (Li et al., GCN 43398). Preliminary photometry is the
following:
