[Aavso-photometry] Re: [AAVSO-DIS] RE: AAVSO special notice 5 object

Hi Tom!  Seiichiro Kiyota indicates that this object
is very red (B-V = 1.49), so that is why your unfiltered
differential photometry will have a large offset from Walter's.
For most novae, it is better to use a standard filter.
At 11th magnitude, you shouldn't have any problem using
a V filter for example.  Classification waits on a
decent spectra.  It is in a tough spot for a single site
to follow, so observations from everyone at all of our
longitudes will be essential to follow its light curve.
