I am a volunteer at the Planet Hunters' site.
Today I found a lightcurve that looks like an LPV, but when I checked the star's type is was type A.
Here is the star: http://talk.planethunters.org/groups/SPH10023764 
Now LPVs are type M and K, mostly, so I don't think this is one.
Maybe someone can have a closer look at it and give his/her opinion.
