The IUE observations of the flare star AT Microscopii while in a flaring state are compared with solar flare observations in a similar wavelength range taken with a slit spectrograph on Skylab. With emission in the UV lines in each case reduced to power (erg s-1), the AT Mic values are between 10**4 and 10**5 times the solar value except for Ly alpha, which is much less. When normalized to the C II 1335 line feature, lines due to Si IV, C IV and He II are significantly more intense in the AT Mic than the solar flare spectra. There is a strong continuum in the stellar spectra, which is compared with that in other IUE flare star and Skylab solar spectra. The continuum intensity is strongly correlated with the C IV 1550 A line intensity, supporting the notion that the continua seen in flare star IUE spectra arise from the heating of the stellar photosphere by UV lines.
