If your setup can handle the dynamic range (by using multiple shorter 
exposures, for instance) you could use the ASAS photometry 
(http://www.astrouw.edu.pl/asas/?page=aasc&catsrc=asas3).  Since the 
star is north of the equator there's no ASAS I-band photometry but you 
can probably use the USNO surveys to get decent enough color information 
on the star(s) you pick out from the ASAS photometry.  As you've 
probably already seen the AAVSO VSP doesn't have a sequence for this star.
