AAVSOnet began in 2005, as the result of a collaboration between observers united by the pursuit of variable star science. Since then, it has prospered, growing to encompass 10+ observatories around the globe, and delivering over 2.9 million images to AAVSO members.
Data Release 10 is now available.
Through a grant from the Robert Martin Ayers Sciences Fund, the AAVSO is performing an all-sky photometric survey. This survey is conducted in eight filters: Johnson B and V, plus Sloan u', g′, r′, i′, z_s and Z. It is valid from about 7th magnitude to about 17th magnitude.
The AAVSOnet Epoch Photometry Database comprises robotically-processed photometry obtained from all images taken with AAVSOnet telescopes. The major component of this database are observations from the Bright Star Monitor network, as these telescopes have taken the majority of images. There are smaller datasets from telescopes that were only operational during the early days of AAVSOnet, covering fewer targets but going much deeper and often with high cadence (time series). For all current telescopes, the intent is to provide public access to older dat
Welcome to the AAVSO's Research Portal.

Everyone’s familiar with the term ‘bricks and mortar’. Many donors prefer to give to specific projects or programs that result in well-defined, tangible goods, such as the new wing of a building, a playground, or furniture and athletic equipment for a recreation center.
