Abstract : Shortwave fadeout durations are compared with associated solar flare characteristics and other features of the solar regions in which the flares occur. Statistical tests show that flare parameters, especially flare importance, have the highest correlations with shortwave fadeout duration. Most other active region features, such as plage area, also show some correlation, but to varying lesser degrees. Cross tabulations of the shortwave fadeout durations and optical features are presented and discussed relative to their use as operational space forecasting aids. (Author)
