  CK Vul (Nova Vul 1670) is one of the most mysterious objects among erupting
stellar objects. Past studies have suggested that CK Vul is a final
helium-flash object resembling V605 Aql and V4334 Sgr (Sakurai's object). The
peculiar outburst light curve of CK Vul, however, had no similar counterpart
among the known eruptive objects. Furthermore, the presence of hydrogen in the
proposed remnant seems to contradict with the final helium-flash scenario. We
propose that the peculiarities of CK Vul can be naturally understood if we
consider a merging of main-sequence stars, following a new interpretation by
Soker and Tylenda (astro-ph/0210463), which was proposed to explain the
peculiar eruptive object V838 Mon. In this case, the 1670 outburst of CK Vul
may be best understood as a V838 Mon-like event which occurred in our vicinity.
