Latitude drift speed of protons in different energy ranges on the dayside and nightside, measured by the CSES satellite. (IMAGE)
Caption
Figure a and Figure e show the F10.7 solar radio flux index. The blue dotted line marks the boundary between Solar Cycles 24 and 25, which occurred in December 2019. In Figures b–d, the average northward latitudinal drift speed is 0.29±0.12°/year on the dayside. In Figures f–h, the nightside shows a significant southward drift from early 2019 to mid-2020, followed by a northward shift from mid-2020 to 2024.
