One-hour geomagnetic forecast
This forecast is based on real time solar wind and interplanetary magnetic field data, provided by ACE spacecraft, which is located in L1 Sun-Earth libration point 1 500 000 km in front of Earth. The one-hour lead time is simply due to solar wind propagation from L1 to Earth.
