The Headquarters of the AAVSO are located in the Clinton B. Ford Astronomical Data and Research Center office structure in the heart of Cambridge, Massachusetts, just a stone's throw from the Harvard-Smithsonian Center for Astrophysics and next to Sky Publishing Corporation. Here are housed the AAVSO's administrative, scientific, data processing, and variable star research facilities. With its own Internet site, the AAVSO is linked directly to astronomers, institutions and observers throughout the world.
