Autonomous Curve Fitting of the Dst index during Geomagnetic Storms

Title: Autonomous Curve Fitting of the Dst index during Geomagnetic Storms

Abstract: A technique has been developed to fit all types of geomagnetic storms identified in the Dst. A lognormal fitting procedure may be used to describe any storm by setting the lognormal standard deviation to greater than 0.9. The fit needs to be constrained around the peak time and the scaling factor determined. This will enable an autonomous method for fitting any type of storm within the Dst. The unique factor identifying the relationship between the main and recovery phase of a storm is the lognormal mean.
