Solar wind and coronal holes

Solar wind speed (velocity) and density values are recorded continuously by an instrument on the SoHO spacecraft. During coronal hole related streams the solar wind speed will generally be moderately high whereas the wind density will be low.

Electron fluence

Electron fluence is measured daily. The plot below shows the electron fluence above the 2 MeV level.

If you have any suggestions on improving the plots don't hesitate to mail your comments to the webmaster
