We performed some follow-up of RS OPHIUCHI 2021 outburst through a TEL 0.1-m f/3.6 astrograph + CCD located in the Heaven’s Mirror Observatory, Australia (MPC code Q56) and operated by Telescope Live network.

On images taken on August 09.42, 2020 we can confirm the presence of an optical counterpart (approximate R-filtered magnitude about +4.8; images were saturated in 10-second exposures) at coordinates:

R.A. = 17 50 13.20, Decl.= -06 42 28.2

(equinox 2000.0; UCAC4 catalogue reference stars for the astrometry).
