The Electrodynamics of the Dayside Cleft Region Based on a Net of Ground Observations in the Svalbard Area

Svalbard is the Arctic archipelago between 10 deg and 35 deg east and 74 deg and 81 deg north. The geomagnetic latitude spans from approximately 71 deg to 77 deg north. This makes Svalbard an ideal place for studies of dayside aurora and processes in the magnetospheric boundary regions. Conjugacy to...

Description
Summary:Svalbard is the Arctic archipelago between 10 deg and 35 deg east and 74 deg and 81 deg north. The geomagnetic latitude spans from approximately 71 deg to 77 deg north. This makes Svalbard an ideal place for studies of dayside aurora and processes in the magnetospheric boundary regions. Conjugacy to stations in Antarctica makes Svalbard even more attractive. The observatory at Ny-Alesund is the master station in a network which also includes field stations at Longyearbyen, Hopen, Hornsund, Bjornoya, and Jan Mayen. International cooperation is essential in this program. Several papers have been presented and many lectures given related to this program. Possible generation mechanisms of dayside cusp auroras including magnetic merging, external pressure pulses and dynamo processes by intruding plasma elements are discussed.
