AAVSO Acronym of the Day: AID
Today's featured AAVSO Acronym is AID – The AAVSO International Database
The AAVSO International Database has over 25 million variable star observations going back over one hundred years. It is the largest and most comprehensive digital variable star database in the world. Over 1,000,000 new variable star brightness measurements are added to the database every year by observers from all over the world. Professional astronomers, educators, students and amateur researchers around the globe use these data.
This is just one example of the tools and programs the AAVSO provides to its members, observers and the astronomical community. Please help support these services by contributing to this year's Annual Campaign.
