Analyzing the light curve data on the Planet Hunters website, I can confirm a period of ~105 days
for KID 9520838... Charts follow of BMJD times 207, 312, 418, 523, 628* ...
*628 a short chart because near end of data available to plot...
Update: I've calculated the period more accurately as 105.32 and the transit epoch as 207.14.
Dotted lines highlight the chart transits below, with the actual transit values in white.
These 'KID 9520838.01' transit values are: 207.14 312.46 417.78 523.10 628.42.
And a quick look at the sky appears clear also (19 17 38.66, +46 07 51.1):
I've calculated this planet's size to be around 3.6 Re. Maybe a little bigger.
That would make it about the size of Neptune. So with transits as precise as these,
this planet candidate should be given consideration as a new Kepler find.
