(Abstract only) The RR Lyrae star AH Leo has a distinct RRab light curve with a superimposed amplitude modulation and variation in time of maximum light. During the 2004 through 2007 observing seasons observations were obtained to try and document observed effects, including an AAVSO observing campaign in 2006. In this presentation we discuss the data validation that was used to bring the campaign data inline with other data, discovered periodicities, and changes in the light curves shape over the four seasons of data.
