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.
