On Thursday, July 2 our own Dr. Bob was a featured guest in an online 1-hour online chat beginning at 1pm EDT (-4 UT). The discussion focused on scientific theories behind epsilon Aurigae and infrared photometric observing techniques. A transcript has been attached to this blog post. Stay tuned for future chats on topics such as visual observing, data analysis, EPO and more.Read more
Dr. Arne Henden, PI of this project and director of the AAVSO, was in the chat room on Friday, July 10 at 1pm EST (-4UT). A transcript is attached to this blog post. He took questions on CCD and DSLR photometry of bright stars. We will host future chats for beginning visual observers and spectroscopy in the coming weeks. Stay tuned!
(Post Chat Update: The transcript has been posted...) Original announcement was:
Join us Sunday, October 25 at 7pm EDT (23UT) for an online chat with Brian Kloppenborg. Brian is Dr. Bob's graduate student at the University of Denver and a key advisor/scientist/everything-person for Citizen Sky. We'll talk about all aspects of CS so bring any questions you have. Just visit this web page to join us.
The chat transcript to our Nov. 18 online Beginner's Chat has been posted. The chat was for those Citizen Sky participants who are relatively new to astronomy and/or the Citizen Sky project. Below is the original announcement:
Everyone is invited to an online "Beginners' Chat" to be held this Wednesday, November 18 at 8 pm Eastern (7 pm Central, 6 pm Mountain, 5 pm Pacific). The goal of the chat is to answer questions about Citizen Sky, epsilon Aurigae, and/or astronomy in general. The tone will be tailored to new participants in the project so this is a great chance to find out more about the project without feeling overwhelmed by the scale of the project.Read more
We've posted the transcript to the Feb. 4 chat w/Dr. Dirk Terrell, who chatted about eclipsing binary stars, space art, robotic telescopes and more. Our next chat will probably be dedicated to new Citizen Sky members. Stay tuned for it's announcement.
The original announcement of this chat is below:Read more
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.
We will be hosting a Citizen Sky online chat this Tuesday at 4pm eastern (+5UT). Dr. Bob, Brian, Rebecca, Aaron and other Citizen Sky and AAVSO staff will be on hand. Topics will include updates on epsilon Aurigae, the upcoming AAS meeting, and ideas for research teams. However, it will be a free chat so any Citizen Sky/VSO topic is welcomed. Hope to see you there!
Note: The chat transcript can now be downloaded from below.

We will be hosting a Citizen Sky online chat TODAY, March 5th, at 11am Eastern (-5UT). Members of the Citizen Sky DSLR Documentation and Reduction Team will be online to answer questions regarding their work and the article published in the April Issue of Sky & Telescope Magazine. This article, titled "Photometry for All in the Digital Age," was written by team members Brian Kloppenborg and Tom Pearson. It describes the work of the DSLR team and explains that DSLR cameras can be quite effective for bright star photometry.
If you have a digital single-lens reflex camera and would like to know more about how to properly use it for photometry, please stop by with your questions. Read more
Members from the MIRA Fourier coefficient team held an online chat session to discuss what needed to be done for the upcoming JAAVSO publication as well as some useful features to be implemented in VStar. The chat transcript is attached to this post.
The group established a timeline:
2011-xx-xx: Generate a list of ~400 MIRAs (completed)
2011-xx-xx: Pre-process these MIRAs to remove discrepant data points between JD 2440000 - 24550000 (deadline needs to be set)
2011-09-23 (or before): Brian provides the team with 10-20 sample MIRAs with known properties (periods, changes in periods, etc.) for testing/training.
2011-10-15: Have analysis of the sample MIRA data complete and report back to the team.
2011-11-15: Abstract and extended outline complete.
2012-01-15: First rough draft of JAAVSO publication complete
2012-03-01: JAAVSO publication submitted.
More details and an updated timeline can be found on the team timetable page (team membership may be required to view this page).
