Spectroscopic classification of ASASSN-18ds as a classical nova

"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."
