Originally broadcast Aug. 7, 2021. John Toone, an AAVSO observer with over 150,000 observations in the AID, and long-time officer and chart secretary of the British Astronomical Association Variable Star Section (BAA VSS), instructs this How-to Hour.
Visual photometry is the original method of recording changes within variable stars and it is as important today as it was 150 years ago when it was the sole means of measuring variable stars. Toone demonstrates the basic methodology, how it can be optimized, explain the effects of color and the relationship with Johnson V, which is the equivalent electronic photometry passband. Toone also introduces you to the world’s most prolific visual observers of variable stars.

Instructor: Lauren Herrington
This instruction is intended for people who have already installed Python: you can find a step-by-step guide to installing Python at the top of AAVSOs preparatory guide, Introduction to Basic Python: https://www.aavso.org/sites/default/files/AAVSO%20pdfs/AAVSO_Introduction_Python.pdf
2) We also recommend skimming through our preparatory guide (url is above).
Webinar description: An interactive session all about how to use Python for astronomy! Well start by reviewing the very basics of Python, from variables to functions. Next, well cover simple usage of a few of the most popular packages for doing astronomy with Python, including live demonstrations of how to manipulate data using Astropy, make beautiful graphs using Matplotlib, and data mine massive remote datasets using Astroquery. This How to Python! session will feature even more interactivity than a typical How to Session, as our instructor, Lauren Herrington, will be taking questions throughout. As the first of three webinars in the AAVSOs How to Python! webinar series, this webinar will set the stage for broadcasts to follow on the topics of asteroseismology and stellar evolution models. Dont miss it!
