The Extreme Ultraviolet Explorer (EUVE) spectroscopic and photometric observations of the dMe close binary system AT Mic are investigated. The photometric observation shows several small flare-like brightening and just at the very end of the observation a large flare. The spectrometer observation has been used to study a model of the coronal differential emission measure (DEM) as a function of temperature. The DEM shows a minimum at ≃10⁶K and a maximum at ≃10⁷K. A number of highly ionized lines of iron (Fe XVIII-XXIII) are identified by means of an EUV synthetic spectrum calculated using the DEM model and the spectral code of Monsignori Fossi & Landini (1994).
