AAVSO Acronym of the Day: LCG

The AAVSO Acronym of the Day today is LCG – The AAVSO Light Curve Generator

Observations of variable stars are plotted on a graph called a light curve as the apparent brightness (magnitude) versus time, usually in Julian Date (JD). The light curve is the single most important graph in variable star astronomy. Light curves allow astronomers to unlock some of the secrets of variable stars. The AAVSO Light Curve Generator allows anyone to plot light curves using data on thousands of stars stored in the AAVSO International Database. It is one of the most popular tools on the AAVSO website. 

This is another example of the tools the AAVSO provides to its members, observers and the astronomical community. Please help support these services by contributing to this year's Annual Campaign.
