Hi Everyone!
This new project of observing an eclipsing binary star in both the Northern and Southern Hemispheres, will be fun and exciting! I hope people around the world will participate. What a great way to bring people together from all walks of life and all cultures!

You'll be part of the original citizen science effort, Eric. Thousands of amateur observers have contributed to AAVSO data for over a century. Some stick with it their whole lives. Let us know how you like it!

Welcome to our variable star project, Eric. The star we are now featuring is Delta Cephei, if you live in the Northern Hemisphere. If you have any questions, please feel free to contact us at this forum. I hope you enjoy your journey!

Hi Eric,
Don't confuse binary systems with variable stars, there are binaries that are also variable (e.g. eclipsing) but not all variables are binaries.
The two currently featured in our program are cepheids, that is, pulsating stars. They expand and contract periodically and their brightness varies as a consequence.
Try finding delta Cephei when you next go outside :)

Cheers,
Sebastian
