Our First Publication: CBET #1885!
CBET #1885 is the first publication of the Citizen Sky project! Congrats to Robin and all the observers who submitted data for the publication. Read the publication and a description of it in this post in our Data Analysis forum.
Looking at the Light Curve: Has the Eclipse Begun?
There are hints in recent visual observations of a decline in brightness for epsilon Aurigae. In this walk through, learn how to read data and the light curve to make your own decision. What do you think? "Is it real, or is it Memorex?"
Looking at the Light Curve III: Thar Be an Eclipse
The third post in our series on light curve analysis looks at both recent data and data from previous eclipses to answer the age-old-question: Who shot JR? Has the eclipse started in visual light?
VStar Light Curve Analysis Software is Now Online!

We are very proud of VStar and thank the team for the many, many hours of hard work that have gone into creating this tool.
A brief description, some simple instructions, and a download link are available on the VStar page. Read more
Online Chat Transcript: Light Curves and Intro Data Analysis
Our special guest was Grant Foster, a long-time variable star data researcher and one of the best around at describing statistics to a layperson. He is recent author of the book Analyzing Light Curves: A Practical Guide. Newbies are encouraged to ask any question, don't be shy! We recommend a quick scan of our new 5-Star Analysis Tutorial before joining the chat. Advanced folk can also attend and ask more advanced questions too, but try to save them for the later half of the talk.
The chat was held on June 9 at 9pm ET (-4 UT). A transcript of the chat can be read here.Read more
Last day to apply for the 1st round of selection for the upcoming Citizen Sky Workshop!
The deadline to apply for the 1st round of selection is midnight (Eastern) tonight Monday, June 14th!
The second Citizen Sky Workshop will be held Friday-Sunday, September 3-5, 2010 at the California Academy of Sciences in San Francisco. We will kick-off the 3-day workshop with an opening reception and tour on the evening of September 2. The focus of this workshop will be data analysis and scientific paper writing. We will have sessions updating us on the science of epsilon Aurigae, how to use VStar for basic data analysis, how to write papers for peer review, how to choose good research questions, doing literature reviews and much more. We also will have a free showing of the new Citizen Sky planetarium trailer on the California Academy of Science's brand-new planetarium dome.
Travel grants are available.
