In the April 2014 Newsletter we published an article on variable stars with close companion causing problems with their photometry.

In this page we give more information and updated tables so you can be aware of the stars that are causing problems or have caused problems in the past.

We will be updating this information with more stars in the future.
If you find a problem similar to those described in the Newsletter article, please let us know.

Something you need to consider carefully, and a question that comes up often with new observers is "How often should I observe my program stars?" The answers depend largely on the type of stars you are observing. The following table is a general guideline. As you learn more about the different types of variables, and the personalities of some of the specific stars you choose to observe, you may decide to observe them more or less often than suggested here.
