The best-fit CLOUDY model of the nebular spectrum obtained on 2015 May 8 shows a hot white dwarf source with Tbb = 1.0 x 10^{5} K having a luminosity of 1.0 x 10^{38} ergs/s. Our abundance analysis shows that the ejecta are significantly enhanced relative to solar, He/H = 2.14, O/H = 2.37, S/H = 6.62 and Ar/H = 3.25. The ejecta mass is estimated to be 1.42 x 10^{-5} Msun. The nova showed a pronounced dust formation phase after 90 days from discovery.
