Overview

The American Association of Variable Star Observers (AAVSO) observing campaigns are coordinated observational efforts focused on specific astronomical objects, particularly variable stars, which are stars that change in brightness over time. These campaigns invite amateur and professional astronomers worldwide to contribute observations, leading to a diverse and comprehensive dataset that can yield substantial scientific results.
