Spectroscopic and geometrical evolution of the ejecta of the classical
  nova ASASSN-18fv
  The optical spectroscopic observations of ASASSN-18fv observed from 2018
March 24 to 2019 Jan 26 are presented. The optical spectra are obtained from
Mirranook, Vainu Bappu and South African Astronomical observatories. The
spectra are dominated by hydrogen Balmer, Fe II and O I lines with P-Cygni
profiles in the early phase, typical of an Fe II class nova. The spectra show
He I lines along with H I and O I emission lines in the decline phase placing
the nova in the hybrid class of novae. The spectra show rapid development in
high ionization lines in this phase. Analysis of the light curve indicate t$_2$
and t$_3$ values of about 50 and 70 days respectively placing the nova in the
category of moderately fast nova. The ejecta geometry, inclination and position
angle are estimated using morpho-kinematic analysis. The geometry of the ejecta
is found to be an asymmetric bipolar structure with an inclination angle of
about 53$^{\circ}$. The ejected mass using photo-ionization analysis is found
to be 6.07 $\times$ 10$^{-4}$ M$_{\odot}$.
