Abstract
An observation of the ultraviolet spectrum (1200 to 1800 Å) during the impulsive phase of a very extended 3B-X3 class solar flare on 27 February 1992 has been obtained with the Solar-Stellar Irradiance Comparison Experiment — SOLSTICE (Rottman et al. 1993). This flare shows a dramatic enhancement of lines formed in the solar transition region. The full disk irradiance (i.e. the Sun as a star) of the resonance lines of C IV and Si IV increased by a factor of 15–20 during the impulsive phase of the flare which is comparable to flux enhancement during stellar flares.
