Solar Transition Region
Abstract
The solar transition region can generally be defined as those plasmas at temperatures between 2×104 and 1×106 K, a temperature regime bridging the CHROMOSPHERE and CORONA. Prior to the space age, the transition region was unobserved although the existence of the higher-temperature corona was known. Spectral lines formed at transition region temperatures are found primarily below 2000 Å where they...
