CRISP Hα line scan images for the reconstructed 54 grid mosaic of July 2, for the time interval 08:15:05–08:20:00 UT. The line scan includes two far wing positions: (a) in the far blue-wing and (d) in the far red-wing. Panel (c) samples the fast spicular structures in the near blue-wing of Hα, and panel (b) samples the upper chromospheric plasma in the Hα core, revealing a complex network of chromospheric loops and dynamic fibrils. The line scan positions, relative to the solar atlas Hα profile, are presented in the subfigure of panel (a), and the specific wavelengths of the scan are detailed in the panel titles. The green and yellow boxes mark features of interest for our investigation.
