The aim of the SWAN (Solar Wind Anistropies) instrument is to monitor the latitude distribution of the solar wind by the Lyman-alpha method. As such, it can be qualified as 'solar wind mapper'.
The main scientific objective is to determine the large-scale solar wind proton flux distribution. The secondary scientific objectives of SWAN include heliopause signatures, the solar corona, the geocorona and the monitoring or discovery of comets.
