The sun constantly emits particles, called solar wind, and magnetic fields, called interplanetary magnetic fields, into space.
The boundary between the Earth's magnetic field and the interplanetary magnetic fields is called the magnetopause. This boundary
is constantly in motion, e.g. due to changes in the solar wind. As a result, waves, known as surface waves, can form on the
surface of the magnetopause. These waves can cause fluctuations in the nearby regions of space. The amplitude of these fluctuations
should decrease with increasing distance from the boundary.

Using a space mission with multiple spacecraft, we observe these waves at different distances from the boundary and present statistical
results comparing the observations with theoretical predictions.
