Panels a)–c): time-slices (s-t plots) along the red trajectory in Fig. 1 for Hα−50 km s^-1a), Hα 0 km s^-1b), Hα+50 km s^-1c), and two AIA channels d)–e). The red parabolas are fits to Hα jet fronts. Panel f): normalized light curves for Hα at λ1 at location L2 (turquoise), Hα at λ3 at L2 (orange), Hα at λ1 at L1 (black), AIA 171 at L1 (blue), and AIA 304 at L1 (brown). Panels g)–h): time evolution of the Hα spectrum along the lines labeled L1 and L2 in panels a)–e). The lines labeled λ1–λ3 are the wavelengths for which a time-slice is shown in panels a)–c). The red lines in panel h) are fits to the Doppler shift of the absorbing feature associated with a jet.
