KIC 5558387 Possible Unlisted RR Lyrae Star at Planet Hunters

This Kepler light curve for star KID 5558379 is being contaminated  by an unlisted background RR Lyrae ( BG RRL) star. The phased curve cue for a possible RRL is shown below:

In this case, the star does not completely own its phased curve and is being contaminated from the BG RRL that is star KIC  5558387. Here is Kian Jek's comment:

"The APOs are significant, 5 and -10 millipixels, and the vector (brightening) points unambiguously to #3 KIC 5558387 as the source of the RRL-like pulsations. Unfortunately we don't know much about this star."
