Variable Star Astronomy

Observing Variable Stars is a fun way to learn about Stellar Evolution and Astrophysics!

I love observing the stars with binoculars from my back yard. Estimating the visual magnitude of those stars and then submitting the observations to the AAVSO (American Association of Variable Star Observers) is a way to contribute to scientific observation and the collection of useful scientific data.

There are many ways to learn about observing Variable Stars. Here are my two favorite places;

  1. Astronomical League Observing Programs -
    Variable Star Observing Program - Astronomical League

  2. AAVSO
    https://www.aavso.org/

I’ve found that I learn more and more each time I search, observe and record data on variable stars. You’ll intimately learn the nightsky, understand how to estimate visual magnitudes of stars, understand the color of stars and how that applies to stellar evolution and many more fascinating aspects of Astronomy.

Reply if you also like observing the stars and would like to submit useful scientific data that professional astronomers will use for centuries to come!

I do like to monitor some variables using my Celestron Origin. S Coronae Borealis is one of them. Here are my images from August and December 2024. Compare S CrB to reference star 1. Quite a difference as the star gets dimmer.
