A model is developed for predicting, in real time, the time-to-recovery for hf signals during a solar X-ray event. The model is designed to give predictions as early in the event as possible, and is backed by an update scheme to correct inaccurate predictions when such are recognized. The model was made possible by the fact that the recovery period of most solar X-ray events can be characterized by an exponential decay with one of four time constants. The choice of time constant can be made by using observations of the rise portion of the event.
