Most of the readily accessible land under the northern-hemisphere auroral zone is in Canada. So 16 of the 20 ground-based observatories are set up in Canada while the four others are in Alaska.
Dr. Eric Donovan, Associate Professor of Physics and Astronomy at the University of Calgary, leads the Canadian part of the THEMIS program. His team of scientists and engineers has worked closely with their American counterparts to develop the ground-based observatories. And they are responsible for fielding the Canadian observatories and retrieving the massive amounts of data from the entire array.
In early November 2007, the Canadian team completed the deployment of the last observatory in Kuujjuaq, Quebec, bringing to operation the Canadian network of 16 observatories (see site illustration, above).
