Is this a Nova?

Hi

I was imaging an exoplanet transit (HAT-P-36b)  last night in V, when a star appeared out of nowhere and gradually got brighter to a magnitude of about 13 (guess) I made a movie of it, I tried to identify the star in every catalogue I own and online including Vphot to no avail..basically at this stage I'm out of my league.

Help!

I have 400x30 second subs in V  and the Nova like event appears at around sub 31 getting brighter for about 38 minutes where my capture stops at sub 400.

I'm Uploading everything to dropbox, it will take a while in case anybody wants to get the calibrated subs.

Thoughts?

Pablo

Hi,

Coordinates match with 2MASS J12330549+4455359, described as an M8 dwarf in Simbad. Possibly a flare star.  Were you using a filter of some sort ?

V Filter

Hi Steve thanks

I was using a photometric V Filter, It appeared out of nowhere and in about 35 mintues got really bright then started fading. I tried to do photometry with Vphot but it couldn't recognize it.
