Spectra of Hα (red), Hβ (green), and Ca ii K (blue) with a PHOENIX spectrum subtracted and scaled for convenience. For comparison the PHOENIX-subtracted flare spectrum (2:58 UT) of each line is over-plotted in black. Different behaviour is seen for the lines, e. g. at 3:14 UT, where the Ca ii line is still double peaked, while in Hα and Hβ the peak at 40 km s-1 has already decayed. Also, the rotationally induced shift of line components is seen, e. g. in Hα the main component, which moves from about –40 (3:14 UT) to +20 (3:41 UT), +30 (3:50 UT), and finally to +50 km s-1 (4:12 UT).
