Eclipsing binary system. Transit depth (see left margin) is greater than 2% and typically planets dim the star light less than that.
Not sure if exactly periodic; in K2VARCAT as Quasi-Periodic, P=2.041, and '2081 (AF Star).' Maybe periodic variable desc best fits?

Another nice transit, but with a duration around 2.4 days and a drop in flux of ~2.5%, this one looks like a LP EB.

CV's typically have dramatic increases in the flux values. See left margin, y-axis grid for spikes. CV's have been found here though. 😃

Dang, seven TCE entries for this system already (11081377). I think we can say this one has been covered.
Maybe two related transits in KIC 6766663, see: http://talk.planethunters.org/#/boards/BPH0000008/discussions/DPH00005iv
Looks like an EB transit at 8-1 to me. Perhaps the UKIRT image supports a binary here. In Prsa V3 as false though.
Maybe something interesting here, KIC 12024065. See discussion: http://talk.planethunters.org/#/boards/BPH0000008/discussions/DPH00005gc
Agree, KIC 9711202 a possible planetary system. See discussion: http://talk.planethunters.org/#/boards/BPH0000008/discussions/DPH000052f
...but could just be coincidental flare activity at what would be the ingress and egress points.
