Two-hour averaged Proton and Helium Intensities

• Near-real-time observations (last two weeks)
  • Proton (in Separate panels)
  • Helium (in Separate panels)
  • Helium-to-Proton ratio
• Archive data ordered by Carrington Rotations (GIF/ASCII)
  • Proton
  • Helium

Level-2 EXPORT data

• The Export Data is available from SOHO WWW server at GSFC
• Description of export data
• Local storage of Export CD images.

Online ERNE datafinder applet (requires Java plug-in)

• Open Database search

Ubuntu Karmic and Debian: You need to install packages 'sun-java6-bin' and 'sun-java6-plugin'.
Ubuntu Lucid: You need to install package 'icedtea6-plugin'.

If you have problems with installing Java plug-in in Mozilla, you might want to consult Mozilla plug-in doc pages, or maybe even Sun Microsystems Java page.
