Variable stars have always been the most intriguing (and fun) targets for observers, professional and amateur alike. I will introduce some of the most common aspects of stellar variability and their significance in astrophysics. I will discuss their common light curves identifiers, and present work by AAVSO observers that has led to cutting-edge scientific discoveries throughout the years. Finally, I will discuss how you can participate in variable star observations from your back yard.
On Saturday September 23, 2017 we had a Grand Opening of our new observatory in Oakham. We also dedicated our Astro-Physics mount which is the center-point of this new facility which was generously donated by Aldrich member Fran Edwards in memory of his late wife Gail.
