Hi Kristine,
I bet the colours of this object puts it in the red giant domain.
From the regularity of the dimming episodes I would classify it as an eclipsing binary but I have seen cases of red giants with Long Secondary Periods (LSP) with light curves reminiscent of eclipses. There doesn't seem to be a clear boundary between the LSPs with the sharpest light curves and the eclipsing binaries. This suggests that dust/disk eclipses might be involved in the LSP scenario, like in RVB stars.
In this particular case I am prone to classify it as an EA-type binary with additional variability coming from the red giant. Do the J-K and B-V support my previous comments?

J-K = 1.06.
B - V = 1.68
It was a star a student found while looking for SRD's in the ASAS data. My gut was eclipsing binary but it was weird enough to ask around. Thanks!
