Fujii-san has reported the following spectrum of Nova Vul 2007.

The Balmer lines showed prominent P Cyg profiles. The FWHM of
Halpha was 1900 km/s. He I lines (4472, 4713, 4922, 5015, 5876,
6678, 7065) were also seen in emission with P Cyg absorption
components. These features indicate that the nova was observed
still in its premaximum state. The continuum suggests that the nova
has a low reddening (perhaps a relatively nearby object).
