3-Day Geomagnetic Forecast

A daily deterministic and probabilistic forecast, for next three days, of geomagnetic activity. Observed values of Ap and deterministic Ap forecasts are provided, followed by probabilistic forecasts for four categories of geomagnetic activity, and deterministic 3-hourly Kp forecasts for three days.

Three-day forecast of Ap, Kp, and Geomagnetic Storm levels

The forecasts for the past 75 days can be found at ftp://ftp.swpc.noaa.gov/pub/forecasts/geomag_forecast/
