important timeframe for V339 Del

Due to the New England winter storm currently affecting the area, phone coverage at the AAVSO may be much reduced until Wednesday. The staff is still available via email, and we suggest using that method to contact us if you need assistance.

Latest reports show a rapid fading of the nova, and the recent IR observations show dust forming.  This is likely the start of the optical dust fade, and so V339 Del may drop dramatically in the next couple of nights.  If you have the opportunity, take a time series!  Beware of the magnitude; it may be fainter than you think.
