This event list contains all solar flares recorded with Yohkoh HXT, SXT, SXS and HXS during the interval between October 1, 1991 and December 14, 2001. In the Yohkoh operation, the observation mode is automatically controlled by the onboard Data Processor, and intense flares trigger the so-called Flare mode. Weak flares, however, are recorded in the Quiet mode without triggering the Flare mode.
