General Notes

There are many reasons to observe EBs. First, it is fun to see a star undergoing brightness changes in just a few hours, and sometimes, changes of the orbital period in just a few years. Next, observing a star provides a context for learning about the star and how to analyze those observations. Finally, one may wish to contribute observations that might be scientifically useful in increasing humankind's understanding of all stars.
