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.

You can mail a check to AAVSO headquarters, or you can make a donation online. Just click the Donate Now button on our home page and select Annual Campaign in the drop down menu.

Maybe today or this week isn't the best time for you to make a donation. That's okay, make a pledge. We'll take you at your word if you promise to make a donation to the Annual Campaign before June 30, 2014. To make a pledge click here.
