New Cepheid?

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

Yeah, I thought that might wake you guys up. :-)

I have been working on the database in preparation for this years data. 
As I was working on cleaning up the W-S stats, I ran across this star:
http://sallman.tass-survey.org/servlet/markiv/template/TassPlot.vm?object_id=6349369 
(Plot)
http://sallman.tass-survey.org/servlet/markiv/action/DataDownload?position=57.1069+59.4424
(Data)
The star is GSC 3729-1127. 2MASS J-K is .895.

Using both Patrick's PDM program and Period98, I get a period of approx. 
5 days. (there are a few slightly more significant frequencies, but they 
are all greater than the Nyquist freq.)
Could this be a Cepheid? The star is quite a bit redder than any of the 
other Cepheids in the area.

Any thoughts?

P.S. I seem to recall a website that had plots of the Fourier 
coefficients for different variables (Cepheid, RR Lyr, Delta Sct, etc.), 
but I can't seem to find it again. Anyone know of such a site?
