The Magnetometer Array for Cusp and Cleft Studies (MACCS) program operates magnetometers in the arctic to study the near-Earth space environment.

Dear MACCS Users,

Our servers are currently partially down for maintenance, and so only data from 2011 through the current time is available. We anticipate that our historical data (1992 through 2010) will be available again before the end of 2017.

Thank you for your patience!
