This module contains several models of intense, observed solar proton events. It also contains hypothetical events including composite cases. Composite cases are formed from the envelope of two strong flare events. Specific models include:

Source	Event	Options
Aerospace	August 1972	Total Fluence, Peak Flux
	October 1989	Total Fluence, Peak Flux
	Composite	Total Fluence, Peak Flux
NOAA	October 1989	Total Fluence
NRL	February 1956	Peak Flux
	August 1972	Peak Flux
	Composite Worst Case	Peak Flux
	90% Worst Case	Total Fluence, Peak Flux (1981), Peak Flux (1984)
	Ordinary	Total Fluence, Peak Flux (1981), Peak Flux (1984)
NASA	August 1972	Total Fluence

These models allow you to explore the effects of realistic and very intense solar proton events on your system. Since more than one model of some events is included, you may also see what impact uncertainties in the models will have on your radiation effects analysis.

New models will be added to this module as they become available. Users are encouraged to recommend published models that are missing from our list.
