Early Photometric and Spectral Evolution of Nova Cygni 2014 (V2659 Cyg)

We present optical spectroscopic and UBV (RI)C photometric observations of Nova Cygni 2014 (V2659 Cyg) from its rebrightening to the Wooden Shape Sorting nebular stage.After the first maximum, the nova underwent several irregular flare-like rebrightenings, with amplitudes up to two magnitudes, accompanied with spectral changes.During the bright state, forbidden lines became weaker; the absorption components of Balmer, He I, Dryer Door Cover Fe II, N I, N II, O I lines strengthened, indicating an increase in the density and mass-loss rate in the form of a wind.
