Models of Active Regions in the Transition Zone from UV Observations
Published online by Cambridge University Press: 12 April 2016
Extract
The Harvard College Observatory UV spectroheliometer aboard the OSO-4 spacecraft has obtained the enhancement of active regions, i.e. the ratio of their intensity to that of the quiet Sun Ia and Iq, for several lines formed in the transition region between the solar chromosphere and the corona (The subscripts a an q indicate active and quiet regions, respectively.)
