- •
A spectrum and multicolour photometric observations are presented for NSV 1907.
- •
NSV 1907 was identified as a deeply eclipsing, nova-like cataclysmic variable.
- •
We find Porb=0.2761069 days and establish the presence of a secondary minimum.
- •
We propose NSV 1907 as a new moderately bright long-period SW Sextantis star.
- •
We find a possible 4.2 day period (the nodal precession period of the disc?).
