Spiridonova (SAO RAS),\nreport on behalf of GRB follow-up team\n\nWe observed the field of the EP251118a discovered by Einstein Probe \n(Jiang et al., GCN 42749; Shi et al., GCN 42754, also detected with \nthe other space observatories, Frederiks et al., GCN 42765; \nWang et al., GCN 42766; DeLaunay et al., GCN 42770; Woolf et al., \nGCN 42771) with the 1-m SAO RAS telescope Zeiss-1000 equipped \nwith the CCD-photometer. We obtained 9 x 300 sec. images Rc band \non 2025.11.19T23:26:31--2025.11.20T03:08:31 (t_mid - T0 = 1.35766 d).\n\nThe OT (Malesani et al., GCN 42751; An et al., GCN 42756; \nBelkin et al., GCN 42758; Busmann et al., GCN 42763; Francile et al., \nGCN 42767; Urquijo-Rodríguez et al., GCN 42773; Lee et al., GCN 42780;\nalso detected in NIR; Yadav et al., GCN 42760) is clearly visible \nin our stacked image with the brightness of R = 21.24 +/- 0.07.\n\nPreliminary photometry is based on the nearby objects from SDSS \n(magnitudes converted with Lupton 2005 equations) \nand has not corrected for the Galactic extinction.",
