000002570 520__ $$aCK Vul was classified as the oldest observed nova. Recent studies have proven however, that CK Vul cannot be unambiguously classified as any known kind of eruptive variable. We present the optical and radio observations of the remnants of the eruption of CK Vul in the year 1670 in order to discuss possible scenarios for this object. We have measured the proper motion which proves that the nebula is attributed to the star observed during its 1670-1672 brightening. A large bipolar nebula of 70 arcsec is discovered in a deep Ha image. Radio observations reveal a barely resolved source placed in the expansion center of the ejecta.
