    There seems to be some odd disturbance on the light graph. Can anyone explain this, for future reference?

    These features are glitches which are caused by large jumps in the raw flux that the correction algorithm wasn't able to cope with. Compare the raw and corrected curves from Andrew Vanderburg here which use a different algorithm, but also have large glitches at the same points. The star is bright (mag 7), so overexposure is likely to be the cause of the problem here. Check out the image plot on the linked page.
