#### Abstract

We study the evolution of V339 Del (Nova Del 2013) during 0.37-75 days after discovery. Spectra from the Liverpool Telescope were collected and analysed to find velocity of ejecta ( v ej ), relative flux of radiance with respect to continuum level ##IMG## [http://ej.iop.org/images/1742-6596/1144/1/012014/JPCS_1144_1_012014_ieqn1.gif] {$({R}_{\lambda }^{* })$} 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 – 75 days can be explained in 7 phases: 1) Initial rise ( t = 0 - 0.6 days); nova is suddenly brighter from V ∼ 11 to ∼6.4. A maximum v eJ is ∼ 2400 km/s. ##IMG## [http://ej.iop.org/images/1742-6596/1144/1/012014/JPCS_1144_1_012014_ieqn2.gif] {${R}_{\lambda }^{* }$} and FWHM first increases and then decreases where this jo...
