"The spectrum is dominated by the strong emission blend of Halpha and
[NII]. In addition to the Balmer lines, strong FeII emission lines are
present, blended with their respective blue-shifted absorption lines. We
interpret the spectrum as that of an FeII-class nova during the
pre-maximum phase.
Unfortunately, the object is slightly saturated on the R acquisition
image. Comparing with the brightest star in the field, USNO
0450.26357218, which is not saturated, we find that the nova is brighter
than R=12.4mag during our observation. This confirms that it is still on
the rise to maximum."
