The corrected geomagnetic (CGM) coordinates are given here for the Earth's surface (altitude 0 km) and Epoch 2005.0 (* Epoch 1997.0). The approximate magnetic local time (MLT) is calculated using the North CGM Pole at geocentric latitude 82.05°N and longitude 277.10°E as a reference (Epoch 2005.0); that means the MLT Noon in UT listed here is not changing with season.

The 1-min MAGIC data are freely available from the Virtual Global Magnetic Observatory (VGMO) page. Higher resolution data (20-sec for MAGIC-1, and 10- or 1-sec for MAGIC-2) are available upon request from the project's Principal Investigator Dr. C. Robert Clauer (bob.clauer at vt.edu). Collaboration with the University of Michigan Magnetosphere-Ionosphere Studies Team (MIST) concerning the data interpretation is encouraged. Any use of the MAGIC data must be properly acknowledged referring the NSF support for the MAGIC data acquisition.

Availability of the Greenland coastal data is limited to specific collaborations established with colleagues at the Danish Meteorological Institute (DMI) and/or the University of Michigan. Any use of the Greenland coastal data must properly acknowledge the Danish Meteorological Institute efforts. Requests for Greenland coastal data can be handled through DMI contacting Dr. Jurgen F. Watermann (jfw at dmi.dk).

    The corrected geomagnetic (CGM) coordinates are given here for the Earth's surface (altitude 0 km) and Epoch 2005.0 (* Epoch of the last year when the station operated). The approximate magnetic local time (MLT) is calculated using the South CGM Pole at geocentric latitude -74.21°N and longitude 126.11°E as a reference (Epoch 2005.0); that means the MLT Noon in UT listed here is not changing with season.
