From top to bottom: Hα, He I D3, Ca II IRT, and Na I D2 flux density evolution during our observing run. The central dashed line indicates the nominal rest-frame wavelength and the outer two dash-dotted lines denote the maximum Doppler shift for a corotating object at 43 deg latitude (28.6 km s−1). The green line represents the expected Doppler shift of such an object if it were to emerge onto the blue limb of the disk 3.72 h into the observation run. Horizontal solid white lines indicate onset times of flares 1 and 2.
