While I agree this is most likely a red variable,
you must keep in mind that KenIchi Kadota's CCD images
are unfiltered.  Therefore, Mati's comments:

does not necessarily support a large amplitude since
the CCD will give a magnitude between R and I for a
red star, which can be 3 or more magnitudes from an
equivalent B magnitude; and in any case,
Mira classification is based on V-band amplitude.

Also, Innes only observed this star over a one-week period.
I haven't read the Circular -- did he see a variation
during this observational period, or did he base his
nova classification on the lack of an equivalent star
on earlier plates?
