It looks like a Be star with rather large amplitude variability: V= 8.09 - 8.23 from Hipparcos+GCPD. Although it's very luminous for this class. Anyway, one full magnitude brightening is even more than the strongest outburst recorded for GCAS stars (delta Sco, ome CMa, gam Cas). So the only thing that's left is to keep observing and confirm the event!
