SoloHI height vs. time map for 28 and 29 March. The map is generated by taking a strip of images at a given position angle, in this case, 86° from solar north, and stacking each time step together. The extended horizontal black line is the boundary between detectors. The y-axis is the radial distance in R_⊙. The features highlighted in Fig. 4 are also noted here, but without differentiating the multiple fronts seen later in the period. The data gaps caused by the instrument shutting off during a spacecraft maneuver are also highlighted.
