  "body": "A. S. Moskvitin and O. I. Spiridonova (SAO RAS)\nreport on behalf of GRB follow-up team.\n\nWe observed the field of the EP260119a (Jiang et al., GCN 43447; \nCheng et al., GCN 43449) with the Zeiss-1000 1m telescope\nof the SAO RAS equipped with the CCD photometer. We obtained \n8 x 300 sec in Ic band on on Jan. 19, 21:33:52--22:18:23 UT \n(t_mid - T0 = 0.90439 days).\n \nThe OT (Fortin et al., GCN 43450; GCN 43455; Eyles-Ferris et al., \nGCN 43452) is clearly detected in our stacked frame \nwith the brightness of I = 20.8 +/- 0.1 (I_lim = 22.0).\nThis preliminary photometry is based on several nearby SDSS stars \n(I-magnitudes obtained with Lupton 2005 transformation) \nand is not corrected for the Galactic extinction. \nMagnitudes is in Vega system.",
