Brian:
I just ordered a U filter, maybe next week I can get some UBV photometry and that will allow a better understanding of BD+59 224's physical nature.

These suggest there must be another hotter component---a hot star
perhaps with a disc in a close binary---so I've been somewhat idly wondering
what sort of pathology is involved.  If there is simply an M giant (say) with
transient emission lines, then U-B will be somewhat larger in value than B-V,
say something close to U-B = 2.0.  If there's a hot star involved, then U-B is
likely to be much less red, say around 0.5, and to me that makes it likely
that this is a VV Cep-type system that's simply been overlooked heretofore.
There's a smaller possibility that there's something more pathological going
on, and it might deserve more thorough study. .....
