Abstract
The extreme-ultraviolet emission measured during a 1992 July 14-17 obs ervation of AU Mic has been studied with lines detected with the short -, medium-, and long-wavelength spectrometers on the Extreme Ultraviol et Explorer. Flares were observed during this period. The time evoluti on of the differential emission measure is presented. The synthetic sp ectrum derived from the differential emission measure is compared with the observed data. An estimate of the density and volume of the emitt ing plasma is obtained by use of Fe XXI lines.
