Abstract:

An imaging riometer system comprising 49 independent beams has been operating at South Pole station since January, 1988. A study of intense, short-duration events from the pre-midnight sector has defined their typical shape as elliptical, with axial ratio 2.3 oriented along the local L-shell. The space-time evolution shows rapid intensifications of the moving absorption patches.
