✦ Synopsis

Broadband sensors aboard the Naval Research Laboratory's SOLRAD 11 satellites measured solar emission in the 0.5 to 3 ~, 1 to 8/~, 8 to 20 ~, 100 to 500/~, 500 to 800 ~, and 700 to 1030 bands between March 1976 and October 1979. Measurements of EUV and soft X-ray emission from a large number of solar flares were obtained. Although solar flare measurements in the soft X-ray bands are continuously made and used as a standard of a flare's geophysical significance, direct measurements of flare EUV emission are quite rare. We present measurements of the X-ray and EUV emission from several flares with special emphasis on the relative EUV response associated with flares in different categories determined by 1 to 8/~ soft X-ray flux. An example of a flare exhibiting an impulsive (nonthermal) phase is included. * Proceedings of the 14th ESLAB Symposium on Physics o[Solar Variations, 16-19 Semptember 1980, Scheveningen, The Netherlands.
