AAVSO Acronym of the Day: VSX
Today's AAVSO Acronym is VSX - The International Variable Star Index
Data on variable stars are constantly changing. New and ongoing surveys are locating new variable stars every day. Corrections to errors in the data are always coming in. But all of this work to refine what we know about these stars is happening at different times and in different places. The mission of VSX is to bring all of that new information together in a single data repository, make it accessible to the public via a simple web interface, and provide the tools necessary for the controlled and secure revision of the data. Created by Chris Wayson and maintained by the AAVSO, VSX is now the most accurate and complete variable star catalog on Earth, containing records for 285,745 stars.
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.
