Individual Hα stationary profiles from our longest run plotted as a function of heliocentric wavelength and time of observation (in the same way as Fig. 4). The corresponding orbital phase is indicated on the right‐hand side. The dashed line shows the fitted radial velocity curve for the Hα+ jet components (one of which appears near 6484 Å at HJD 2,451,364; other, weaker jet components may be blended with the stationary Hα line in the preceding two nights). The nearly vertical dotted line traces the outward motion of a blueshifted absorption trough.
