Komarov\n(SAO RAS) report on behalf of the GRB follow-up team.\n\nWe observed the field of the GRB 241026A (The Fermi GBM team,\nGCN 37894; Melandri et al., GCN 37896) with 1-m telescope of SAO RAS\nequipped with the CCD-photometer on October 26, 23:02:35--23:18:09 UT.\nObservations started 20 minutes after the trigger.\n\nWithin the prompt enhanced Swift-XRT error circle (Evans, GCN 37897)\nwe detected a single uncatalogued source (possible GRB afterglow)\nwith the coordinates\nR. A. (J2000) = 19:33:36.06,\nDecl. (J2000) = +57:59:09.04 +/- 0\".5\nand brightness of R = 20.04 +/- 0.14 calibrated against nearby\nUSNO-B1 stars (R2 magnitudes) and not corrected for MW extinction.\nFurther observations are ongoing.\n\n"
