Solar and Solar Wind Disturbance Predictions

Abstract

A prediction of 75, a relatively low number, has been made for peak sunspot number for solar cycle 24. Direct measurements of the solar wind magnetic field strength and speed became routinely available in the 1960s. The Interdiurnal Variability Index has been used to reconstruct the magnetic field strength of the solar wind, thereby extending the data back for a total of about 125 years. With these results and the Interhourly Variability Index, the speed of the solar wind has been determined for the same period of time. Other results include the establishment of bench marks for the extreme limits of solar-terrestrial activity and validation of the Proton Prediction Study tool for short term alerts of solar particle events.
