I'm curious why the interest?
Qrion has thousands of variable stars in it. What would be
interesting would be to follow it with filter photometry. MY plate is
pretty full right now so I can't devote instrument time to it. It
would be an easy CCD BVRI project, however. It might give a good idea
about the star colors and show different eclipse depths in different
bands.
