EP241021a: SAO RAS optical observations

We observed the field of X-ray transient EP241021a (Hu et al., GCN 37834) with the 1-m telescope of SAO RAS equipped with CCD-photometer. We obtained 9 x 300 sec. images in Rc band on October 23, 19:27:12--20:17:25 UT (t_mid - T0 = 2.6141 days). We clearly detect the OT (Fu et al., GCNs 37840, 37842; Li et al., GCNs 37844, 37846; Ror et al., GCN 37845; Zheng et al., GCN 37849) in our stacked frame with the brightness of R = 21.81 +/- 0.06 calibrated against nearby SDSS stars (magnitudes converted with Lupton 2005 equations) and not corrected for the Galactic extinction.
