An Early Proxy for Solar Flare Soft X-Ray Fluence

Abstract

The relationship between the soft X-ray fluence of a solar flare and the combination of its rise time and its peak flux is investigated in order to derive a proxy for the fluence that can be estimated at the peak of the flare, i.e., significantly earlier than the "end" of the flare (by convention, the half-power point on the decay). The result will be used in forecasting solar energetic particle events.
