Irradiance Observations of the October 28, 2003 X-17 Flare
Abstract
The Solar Radiation and Climate Experiment, SORCE, carries four instruments that measure solar irradiance -- both total solar irradiance, TSI, and spectral irradiance from soft X-rays, ultraviolet, visible and near infrared. During the X-17 flare at 11:00 UT on October 28, 2003 the SORCE instruments were in ideal configurations to record increases in TSI and at most observed wavelengths. The X-ray and UV irradiance originating in the transition region and corona increased by factors as large as fifty. This large flare also provided the first measurement of an increase in TSI, a unique measurement that places an important new constraint on the energy release during the flare. This report is a survey and interpretation of the irradiance variations observed during this X-17 flare.
