Final Week of Astro-April: SEVEN more online talks!

The AASVO's Citizen Sky Project has been producing a series of online talks as a part of a month-long celebration called Astro-April.

In the last couple of weeks we have presented 5 online talks on various astronomical subjects.  (If you missed any of them, recordings are posted on the main Astro-April page.)  The speakers have been engaging, the questions have been thoughtful, and we've given away $250 in "door" prizes!

JAAVSO Call for Papers for Special epsilon Aurigae Issue


for a special edition of the

Journal of the American Association of Variable Star Observers

Special Notice #246: Continued Monitoring of epsilon Aurigae

August 8, 2011: The bright star epsilon Aurigae has emerged from its most recent eclipse that began in August, 2009. A BVRIJH light curve for the last 365 days of the eclipse can be viewed at the following URL.

Effects of dust on light-curves of ε Aur type stars (updated)

100728 Update: Dr. Budaj has offered a short description of the paper with a nice illustration, which can be read via the Citizen Sky forums.

The following is an abstract for a paper recently been posted to ArXiv (and accepted for publication in A&A Letters). The paper is based on your AAVSO observations of apsilon Aurigae and acknowledges AAVSO support.
