epsilon Aurigae

Below you will find links to materials that were developed in the first three years of the Citizen Sky Project as part of the epsilon Aurigae observing campaign.  Additional materials are available at the original Citizen Sky Website, which will remain intact as an archive of the Project's activities.

AAVSO Binocular Program

The AAVSO Binocular Program consists of 153 stars in the northern and southern hemispheres. They are mostly semi-regulars and Miras, with a few other types sprinkled in. Most of the stars range between 3.0 and 9.5V and can be observed best using simple hand held binoculars. 

Astro-April Webinar Recordings

It's Astro-April at Citizen Sky!


Recordings for all Astro-April online talks have been posted below!

To celebrate the achievements of the Citizen Sky Project and to introduce our participants to the wider world of astronomy, we planned a month-long celebration called Astro-April, which took place in April of 2012.  We scheduled webinars throughout the month on various variable star topics. We also gave out many awards and prizes throughout the month.

Citizen Sky Workshops

First workshop: Science and observing

The first Citizen Sky Workshop was held in early August of 2009 at the Adler Planetarium in Chicago, IL. Here you will find links to videos and presentations from some of the fascinating talks that were held during that workshop.
