Rapid blue-shifted excursions in Hα, Ca II K, and Mg II k. Top: spectroheliograms and slit-jaw as labeled with overplotted color-coded RP bins. Bottom: spectra for the RPs following the same color code. The dotted pink profile is the difference between the average Hα profile (dashed) and that of RP−3 in arbitrary units. The vertical dashed-dotted line highlights the proximity of the latter with the minimum of the Ca II K3 RP−3 at −38.6 km s−1. The dashed red lines in the SJI indicate the extent of the IRIS rasters.
