International Epsilon Aurigae Campaign 2009 - 2011
8 February 2010
Every 27.1 years the very mysterious variable star epsilon Aurigae undergoes an eclipse that lasts nearly 2 years. This is an easily found 3rd magnitude star visible from the northern hemisphere. It is one of a trio of stars that form a small triangle called "The Kids" just southwest of Capella. While there is no shortage of theories, the precise nature of the star system remains a mystery. During the last eclipse 1982.1984 a Campaign was formed to observe and try to figure out answers. Great deal of information was obtained, yet there are still many unanswered questions. Beginning in the summer of last year (2009) the latest eclipse started. In 2006 an International Campaign was again formed and an official web site devoted to the current eclipse created.

We have amateur and professional observers from around the world (18 countries) providing photometric and spectroscopic data of the star system. Some observers are also providing interferometry and polarimetry data. We have published 16 Newsletters so far for this Campaign. We encourage anyone interested in this star system to join the Campaign.
