Short summary

We analyzed the average magnetopause position influenced by solar winds and interplanetary magnetic field (IMF) using data from the Time History of Events and Macroscale Interactions during Substorms (THEMIS), Radiation Belt Storm Probes (RBSP), and Magnetospheric Multiscale (MMS) mission from 2016–2020. Minimal movement occurred during substorm phases. The magnetopause moved to its closest inward position during the growth phase and relaxed from peak to recovery as in Shue's model.
