  We study the evolution of V339 Del (Nova Del 2013) during 0.37 to 75 days
after discovery. Spectra from the Liverpool Telescope were collected and
analysed to find velocity of ejecta, relative radiation with respect to
continuum level, and FWHM of the radiation. The evolution of light curve was
explained by adopting an ideal nova light curve as criteria. We found that the
evolution of V339 Del during t = 0.37 to 75 days can be explained in 7 phases:
1) Initial rise (t = 0 - 0.6 days, 2) Pre-maximum halt (t = 0.6 to 1.2 days),
3) Final rise (t = 1.2 to 1.5 days), 4) Maximum (t = 1.5 to 2.5 days), 5) Early
decline (t = 2.5 to 35 days), 6) Transition (t = 35 to 60 days), and 7) Final
decline (t = 60 to approximately 75 days).
