The Unresolved Active Region Corona

Jonathan Cirtain

Recent results of the intensity decrease as a function of altitude in Active regions have found that hydrostatic scaling laws can accurately model the observed decrease in intensity. Furthermore, the scale height temperature derived from the observations for Quiescent Active regions is found to be both constant in space and time. However, flaring Active Region emission has been found to have a multithermal background, and the scale height temperature has been observed to increase just prior to the onset of a flare. This observation may be a useful technique to predict solar flares, and the instruments on Solar-B may prove ideal for this type of investigation.
