Question about a star

Hello everybody.
When classifing I found this star:
http://talk.planethunters.org/#/subjects/APH0000wre
Metadata
EPIC no: 211001716
2mass id: 04134957+2300049
sdss id: unknown
Mag: 10.781
Jmag: 9.478
Hmag: 9.075
Kmag: 8.97I was wondering, is it variable? This only big huge depth at the day 13 is it normal? Maybe I am just misinterpreting after the story of KIC 8462852.

Variation on this scale (about 1 - 1.5%) is not unusual. It helps to check the vertical scale.
It repeats semi-regularly with a period of about 20-22 days and is most likely just instrinsic variability of the star. I am guessing it might just be variations in surface brightness as the star rotates.
KIC 8462852 is a completely different matter. Its light curve has a few sudden drops of up to 20% which do not repeat regularly and also have unusual shapes.
