No one knows what Nova Del 2013 will do next, but there are some tantalizing possibilities.
The current AAVSO light curve for Nova Del 2013
So far it appears Nova Del 2013 is a 'slow nova', type NB in VSX. By definition, it takes 150 days or more for a slow nova to fade by 3 magnitudes.
Sometimes "or more" can mean a lot of other exciting goings on.
