(super)nova?

Is this a nova-type lightcurve?

No supernova (outburst lasts for months!), but maybe a CV (cataclysmic variable). Very interesting light curve indeed. KID 210282487

Wow, that is something else! Could someone from the science team please tell me a bit more about it? It would be a great feature on #dailyzoo ... !!

Not a science team member, but maybe this will help

Thanks, Edd. I'd like to get a scientist to confirm that it is indeed a dwarf nova or CV before I post it, though. I should be able to find one and ask. Thanks!!

Ok, here is VSX entry
It is CSS 130516:111236+002814 a U Geminorum-type variable, quite often called dwarf novae

Well, according to this recent study the example below is what we are looking for regarding supernovae(!)...
"Astrophysicists catch two supernovae at the moment of explosion"

"Shock Breakout and Early Light Curves of Type II-P Supernovae Observed with Kepler"

(Studied in paper are KICs 8480662 and 10649106)

Just an article about an interesting and (possibly) observed phenomena where a large star will mostly skip the CV event and transition directly to a black hole.

Also here is what a CV maybe a DN looks like in a K1 TPF pixel animation (KIC 9071514). And what you seen here is often as good as we can get with these images, but at least it does show the dramatic increase in brightness:
