IMAGE was launched on March 25, 2000. IMAGE is obtaining data on the high-latitude northern-hemisphere ionosphere and magnetosphere, and also the magnetospheric equatorial plane for roughly 20 hours/day.This information is transmitted in real time. Southwest Research Institute manages the IMAGE project and leads the IMAGE science investigation. Through a partnership between NASA, NOAA, the Communications Research Laboratory (CRL) in Japan, and a network of additional ground stations, the images will be received and transferred to the NOAA Space Environment Center. The University of California, Berkeley and CRL will dedicate part of their available antenna tracking to the IMAGE satellite. Other organizations that may also participate in tracking IMAGE are NOAA, Rutherford Appleton Laboratory (UK), and the US Naval Academy (Annapolis, MD). NASA’s Goddard Space Flight Center, Southwest Research Institute, the IMAGE instrument teams, NOAA/SEC, and CRL have jointly developed the software that will process the real-time data and make the images available.

These images will provide a real-time view of the aurora as they respond dynamically to the changing Sun. In addition to their natural beauty, the aurora are also an indication of disturbed space weather that can affect radio propagation, communication systems, electrical power systems on the ground, and satellites and astronauts in space. It is anticipated that these data products will have research and operational value, both as immediate indicators of space weather conditions and also as input and validation data for space environment models.
