The present detection of oscillations refers to quasi-periodic modulation
with an amplitude of 0.5-0.7 mag and a period of 6-8 days, superimposed
on the smooth decline of a fast nova. Similar oscillations were best
observed in GK Per and V603 Aql (see the light curves in some textbook of
varaible stars).
Our knowledge in the origin of oscillations is still poor.
