Abstract

(Abstract only) We present rapid cadence U, B, and V photometry of e Aurigae during its 2009–2011 eclipse. Data are analyzed to look for both periodic and random variation. Observations are presented from two observers. The first is from Rockyford, Alberta, Canada, and used a ST-7 and ST-8XME with 50mm and 135mm lenses, respectively. This observer recorded continuous filtered time series up to 11 hours long. The second is in Hereford, Arizona, and used a ST-10XME with a 0.36-m SCT.
