Ould-elhkim (LAM) report on behalf of a larger collaboration: We observed the field of the EP260214b (Yang et al., GCN 43744) using the T120cm telescope at Observatoire de Haute-Provence (France). We obtained 40 minutes of exposure in the r-band starting at 01:37:37.6 UT on 2026-02-15 (~3.6 hr after the trigger). In the stacked image, the optical counterpart detected by He et al.(GCN 43745), Watson et al. (GCN 43747), and Perez-Fournon et al. (GCN 43750), and measured at a redshift of 1.208 (LeFloch et al., GCN 43749) is visible with a preliminar magnitude of: r = 21.22 +/- 0.13 mag (AB) The photometric calibration was performed using nearby stars from the PanSTARRS catalog and the STDWeb/STDPipe tools (Karpov 2025), is in the AB system, and is not corrected for Galactic extinction. We acknowledge the excellent support from Observatoire de Haute-Provence.
