I detrended this with a 33point moving average and tried folding it in Open Office Calc, there are clearly transits but could not get them to line up neatly, period is as zoo3hans said 0.35 days so this is one dizzy planet! hard to tell the duration but its more than 30mins but less than a hour.
Given the trouble I had folding it I suspected TTVs so I fed the detrended LC into AKO here http://www.extrasolar.us/AKO/AKOimage.php?
And got this with a period of 0.35days
That looks a wavy line to me, and I think with maybe two patterns, so maybe there are 2 or even 3 planets here, I've looked and can't see any obvious transit events from other planets if there are in fact any.
looking here http://talk.planethunters.org/#/boards/BPH0000007/discussions/DPH0000npe and noting that for this star J-H=0.526 & H-K=0.148, I am going to guess that this is a middle of the road K class star with Rad=0.65 Sol and Mass=0.7 Sol. using this http://www.kianjin.com/pcalc.html that gives a rather toasted planet of radius 1.7Radius Earth at just .009 AU and a central transit should give a duration of 0.94hours. But I suspect this isn't a central transit.

I'm not sure how to pin down if there are TTVs or not, and if so the periods of any bodies producing them, so I tried simply feeding the detrended LC into NASA's Periodogram service. It didn't give me any periods greater than about half a day so it didn't seem to help much, but it did say the phased period is actually 0.349910 days
