PREDSTORM is our real-time solar wind forecast for the Sun-Earth L1 point. It is updated every 30 to 60 minutes. It uses data from STEREO-A, or, if they are not available in sufficient quality, data from the previous solar rotation about 27 days ago. Both methods have been tested by some studies and show promising results. Work on a live forecast verification is underway.

Please note: Currently, this forecast only works for high-speed solar wind streams, and will fail during times when solar storms, also known as solar coronal mass ejections, impact the Earth's magnetic field.

The data shown in the plot are available in ASCII format here.
