New Tass Variable

[Michael Sallman <msallman@pro-ns.net>]

Anyone have any thoughts on this star?
http://sallman.tass-survey.org/servlet/markiv/template/TassPlot.vm?object_id=3750217

I can't find a period that fits the data (TASS or ASAS or NSVS). At first 
(because of the color), I thought it might be a RR Lyr even though the plot 
doesn't "look" like one. There might be some tricky aliasing going on to make it 
look different. Same for an eclipser with a large temperature difference between 
primary and secondary.
So, could it be some kind of CV? Though it's bluer at minimum than most of the 
other CVs in the TASS data. And I'm not sure if CVs are normally Xray sources, 
but Vizier doesn't show any within 5'.
If it's none of the above, what other types of variables would fit this
star's amplitude/color/color variation?
Maybe someone with more skill than I would like to take a look at the data?

It isn't listed on the ASAS variables page, though it's obviously variable in
their data as well.

And here is the NSVS/ROTSE data:
