the latest 48 hours of solar wind data

brought to you by the CELIAS/MTOF Proton Monitor on the SOHO Spacecraft

talking sun There is a problem with the motor controlling the High Gain Antenna on the SOHO spacecraft.   Science data coverage may be less than complete for 1-2 weeks every 90 days (when the spacecraft gets 'flipped').   The next "keyhole" period can be found in this table.
