Bouquin (NOT) report:\n\nWe observed the field of EP260507a detected by EP (Fu et al., GCN 44488), using the 2.56-m Nordic Optical Telescope (NOT) equipped with the ALFOSC camera. We obtained 3 x 300 s frames in the Sloan g, r, i-band, respectively.\n\nThe optical afterglow (Corcoran et al., GCN 44489; Sankar et al., GCN 44490; Jiang et al., GCN 44491; Kumar et al., GCN 44492; Eyles-Ferris et al., GCN 44495) is detected in our stacked images. Preliminary photometry results are as follows:\n\nTmid-T0(hr)    Mag    MagErr  Filter\n   9.54       23.04    0.12      r\n   9.82       23.61    0.17      g\n   10.10      22.77    0.17      i\n\ncalibrated with Pan-STARRS DR2 stars in the field and not corrected for Galactic extinction.",
