Catch the "Demon Star"
Note: Next eclipse is Dec. 23. Algol, a.k.a. "The Demon Star" has some very well-timed eclipses for the month of December. It's a very bright naked-eye object and an entire eclipse can be seen in 4-5 hours. It's great training for epsilon Aurigae!Read more
Mini-Campaign on an Eclipse of Zeta Aurigae
Brian is leading a mini-campaign on zeta Aurigae. It is undergoing a short eclipse (compared to epsilon Aurigae) with a dip of only 0.1 mag sometime this month. Thus it will be quite a feat for even advanced observers. Up to the challenge?

Supergiant Binary Stars - Video from Workshop
The first video from the Chicago Workshop has been posted to the forums. It's a talk about supergiant stars by Dr. Doug Welch. Consider this a sample of much more video coming soon.
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?
Avoiding Bias: Simonsen's Rules for Variable Star Observing
Check out Mike's advice for avoiding bias. Among my favorite advice:
If you see the observations of some other observer(s) beforehand-Read more
- Assume they are lying to deceive you!
- Know they are bad observers, so their opinion is worthless!
- They could be, and probably are, completely crazy. How many variable star observers have you met? I rest my case.
Looking at the Light Curve II: Hints of an eclipse?
You're sending in more data and it's helping! We have an updated forum post about new evidence for the eclipse in the light curves. What's your say? Is it starting? Read the light curve and make a prediction.
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?"
