Abstract

Abstract A deep VLA map of the X-ray binary Cygnus X–3, obtained at 6 cm wavelength in B configuration, is presented. The map clearly shows the symmetric ejection of plasma condensations along a position angle close to the North–South direction. An overall jet-like bipolar morphology, with a full size of about 5 arcsec is evident. The jet condensations are detected at the 0.3 mJy level with a very high significance (SNR>10), and they are very likely to be the remnant of the strong Cygnus X–3 radio flare that occurred three months before our observing run. Accepting this association, the ejection velocity derived for both condensations is ∼0.6 c.
