Andrew Drake has flagged this object as being at mag 13.01 and as a possible CV/Var over on the Catalinae VOevent pages 

http://voeventnet.caltech.edu/feeds/Catalina.shtml

details in this table

and if you click the 63113 in the LC (lightcurve) column you should get interactive use of this CSS lightcurve :-

move the mouse cursor over any datapoint in the javascript popup and note the date and mag values top left of box.

He also notes in the above table that this here object is in GALEX, and indeed it is with GR4 FUV-NUV colour -0.04.  Pretty "blue" as the jargon has it.

Fairly white to blue in various usno catalogue mags too.

a UGSS past missed, summat exotic like the recent eclipsing Polar Denis Dennisenko and his associates showed and elucidated?

The USNO B2 mag _suggests_ a past eruptive event.

Dunno.

I do know this though, it is formally CSS090201:090210-113032 declared and identified as a potential CV via Andrew Drake on the Catalina VOevent site, via a service they generously offer and are not mandated nor obliged to offer, and upon which Andrew Drake as for some little time now generously coralled and highlighted the outbursts of known and new cataclysmic binaries, and it is not OT_ anything come across by research from elsewhere.   The Catalina site highlights all that is needed to be known to recommend any follow up work the CV community may or may not be inclined to point at it.

And I don't care who the hell such pedanticism upsets.  It's not often professionals give instead of asking for.  CSS transient service has been very useful for keeping the CV community with objects of interest the past little while.

Cheers

John
