Abstract (from CDS):

We present simultaneous Hα, NaID1, D2, and HeID3 spectroscopic observations on the RS CVn system UX Ari. We have found a dramatic increase in the excess Hα emission equivalent width by a factor of 2 in an interval of 1 day that indicates the beginning of a strong flare in this system. The presence of the HeID3 in emission in coincidence with the enhancement of the Hα emission confirms the detection of a flare. The application of the spectral subtraction technique reveals that the core of the NaID1 and D2 lines are also filled-in by chromospheric emission.
