THE CLUSTER MISSION: SOME RESULTS AND PLANS RELATED TO ELECTRIC FIELD OBSERVATIONS.
Mats Andre, Swedish Institute of Space Physics, Uppsala division
The Cluster mission is a unique European Space Agency mission to study how
the solar wind affects the magnetosphere of the Earth. This is the first time that
four identical spacecraft have flown in formation around the Earth. A brief
overview of the mission, and in particular the electric field instrument, is given.
Some examples of recent observations are presented, including waves over a
wide range of waveleghts at the magnetopause. Plans for future studies are also discussed.
