This is the high-resolution space weather forecast page based upon the Hakamada-Akasofu-Fry (HAF) solar wind model.   We also provide real-time space weather forecasts based upon our standard model (5x5 degree boundary conditions) as soon as possible following significant solar events.

High resolution forecasts:

Solar wind speed, density, and magnetic field time series

Ecliptic plane heliosphere

1x1 Degree photospheric and source surface maps:

The source surface flux-tube-divergence-factors (FTDF) are produced by mapping the coronal magnetic potential field, calculated using the method developed by K. Hakamada (Solar Phys., 159, pp. 89-96, 1995).  FTDF are inversely related to the solar wind speed observed at Earth.
