EP241021a: further 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 12 x 300 sec. images in Rc band on October 26, 20:39:47--21:53:44 UT (t_mid - T0 = 5.6728 days). We 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; Moskvitin & Spiridonova, GCN 37850; Pugliese et al., GCN 37852; Pérez-Fournon et al., GCN 37858; Bochenek & Perley, GCN 37869; Kumar et al., GCN 37875; Busmann et al., GCN 37877; J-Jin et al., GCN 37892) in our stacked frame with the brightness of R = 23.10 +/- 0.18 calibrated against nearby SDSS stars (magnitudes converted with Lupton 2005 equations) and not corrected for the Galactic extinction.
