Planet Hunters forum Talk members have identified KID 2581554 as a planet candidate with a very short period.
Kian Jek:
The host is a heavily spotted Type K subgiant with a rapid rotation of ~8 days resulting in a lot of variation which made the 17 transits hard to isolate. There appear to be no correlated APOs. Transits were masked out by hand and the curve detrended:
The light curve is then folded by hand again to obtain a period of 47.148 and a rather good-looking transit curve:
The transit duration is very short because of the high impact parameter of 0.93. The transit depth corresponds to a 7.47x RE planet at a distance of 0.28AU and a Teq of 577K.
UPDATE: Phased APO plot for Q5 and Q9:
