Full public access to all the data from the University of Iowa cameras on board the Dynamics Explorer-1 and the Polar spacecraft is now available online. All the images from 10 years of operation (1981-1990) of the original discovery instrument on the Dynamics Explorer-1, as well as all the images available since the launch of Polar in February of 1996, are provided by the University and, more recently, by the International Solar-Terrestrial Physics (ISTP) project personnel at the Goddard Space Flight Center (GSFC). The availability of these comprehensive data sets, which include both auroral and atmospheric hole images, is the result of many months of software efforts at The University of Iowa and GSFC. "Interested parties are encouraged to independently explore and analyze this extensive data base," notes University of Iowa physicist Louis A. Frank.
