Sweden's first satellite, launched on 22
February 1986 from Kourou, French Guyana, into an 800 by 13,500 km polar orbit.
It carried five different instruments built by groups in Sweden, Denmark,
France, Canada, and the United States. The Alfvén Laboratory was responsible
for the instrument measuring the electric
field. The main scientific objective
of the project was to investigate the auroral acceleration processes, by
flying through the region where the acceleration is believed to take place.
Operations ceased on 12 May 1987 but data analysis is still in progress.
The group has authored or co-authored more than 60 refereed publications
based on data from the electric field instrument on Viking.
Electric Field Data are available online.
