Abstract

The SWAN (solar wind anisotropies) Lyman photometer project is described. It will map the interplanetary hydrogen emission every other day. From these sky maps, the latitude distribution of the solar wind mass flux from equator to pole can be measured, as well as the variation of this distribution. Solar wind mass flux at high latitude is a key boundary condition to the dynamics of the expansion of the solar wind, particularly in the coronal holes, and correlatives studies conducted with other SOHO (solar and heliospheric observatory) coronal instruments. Secondary objectives include the monitoring of known comets, the possible discovery of new comets, and coronal observations.
