Abstract

An International Campaign and Web site were started in May of 2006 for the 2009–2011 eclipse of the mysterious star system e Aurigae. Photometric and spectroscopic observations of the eclipse were coordinated and reported. The eclipse started in the summer of 2009 and lasted until the spring of 2011. During the campaign twenty-four newsletters were published on the web site and made available free as .pdf files to read and download. Twenty-six observers from fourteen different countries submitted photometric data in the UBVRI bands. Over 3,600 high-quality photometric observations were submitted with nearly 2,000 observations in just the V band. This paper discusses the Campaign and report the results.
