The preceding paper (Hebb et al. 2006) presented the scientific rationale for monitoring AU Mic for planetary transits. In this paper we discuss the analysis of the data, which yields 0.003 mag rms differential photometry, even through moderate cirrus. Our observations were obtained with the CTIO-Yale SMARTS 1.0-m telescope and OSU Y4KCam during a one-month observing run in the Summer 2005. We present typical light curves and how our four filters allow us to discriminate against stellar activity. We show one interesting event, and discuss our limits for detecting planets that transit AU Mic.
