Comparisons of the Hα line profiles for different observations of the same two objects. Upper panel: LOri068; one of the objects we suspect esperienced a flare during the Keck/LRIS observations (R ~ 2700). Some asymmetry can be seen in the line even though the resolution of the spectrum is moderate. Lower panel: LOri109, another object suspected to have a flare for which no asymmetry in the line has been found.
