  This one has an interesting curve. If you look at all 3 images (and zoom in), it has several dips but it doesn't look like an eclipsingbinary and there are many of them, so they might be something other than planets. What do you think it is?

  I agree this is very intriguing. It appears to be a semi-regular variable with a period of around 2.2 days, but there are also nice periodic U-shaped dips with a period of around 1.85 days starting at BKJD 2063.33 which repeat thoughout all three images. The clearest dips are consistently about 0.2 days long and 2% deep. Maybe it really is a planet. It would be interesting to read other opinions.

  There are some other stars nearby that might be contaminating the lightcurve.

  Not really, they are far away

  Could be a binary, looks extended in UKIRT and CFHT image

  Thanks for the analysis. That looks pretty convincing to me.
