The recurrent nova and symbiotic binary RS Oph erupted again in August 2021 for its eighth known outburst. We observed RS Oph 34 days after the outburst at 5 GHz with the European VLBI Network (EVN). The radio image is elongated over the east–west direction for a total extension of about 90 mas (or about 240 AU at the Gaia DR3 distance d = 2 . 68 + 0 . 17 − 0 . 15 kpc), and shows a bright and compact central component coincident with the Gaia astrometric position, and two lobes east and west of…
