Helium line formation during the decay phase of a small two-ribbon flare
During a coordinated campaign (SOHO JOP 139) which took place in May 2001, a small C-class flare was observed both with SOHO instruments and with the Dunn Solar Telescope of the National Solar Observatory at Sacramento Peak. Data for helium line formation in the active region prior to the flare have...
