O vi(λ1032   Å) spectra, residuals, and lightcurves Nos. 37 and 38 of the FUSE time series of AD Leo. During spectrum No. 37 a flare happened in AD Leo (see Fig. 1), whereas the corresponding lightcurve of No. 38 shows no variation although we detect a higher mean countrate which possibly indicates that exposure No. 38 belongs to the decaying tail of the flare. Both line profiles differ from the quiescent profile of O vi(λ1032   Å). The line wings in both spectra are broader than in the quiescent case, profile No. 37 shows a red wing enhancement, whereas No. 38 shows a distinct blue wing enhancement, which is shifted by  − 84 km s^-1 (measured from maximum to maximum of the left-most fit to the line center of O vi(λ1032 Å)). A multi-Gaussian function was used to fit the observed profile. The red solid line represents the multi-Gaussian fit, whereas the thin black solid lines represent the single Gaussian components of the fit. The exposure time (after screening) for exposure No. 37 was 2020 s and for exposure No. 38, 1186 s.
