EPT measurements of supra-thermal protons between 30 Nov 2023 10:46 and 10:52 show significant substructure on timescales comparable to and shorter than the proton gyroperiod of four to five seconds. The format is similar to that of Fig. 7, but intensities have been multiplied by energy to show the substructures more clearly. Time periods (4) and (5) are also indicated. Shock #2 is indicated by the vertical red line, and the beginning and end of the likely magnetic switchback that causes the dynamical behavior in time period (5) are indicated by vertical dashed blue lines.
