Interplanetary (IP) shocks are important sites of particle acceleration in the Heliosphere and can be observed in-situ utilizing spacecraft measurements. Solar Orbiter provides observations of interplanetary shocks at different locations in the inner heliosphere with unprecedented time and energy resolution in the suprathermal (usually above 50 keV) energy range, thus opening a new observational window to study particle acceleration.
We first discuss the behaviour of a strong IP shock observed as close as 0.07 AU by Parker Solar Probe and then by Solar Orbiter at 0.7, highlighting how the shock and energetic particle production change for different evolutionary stages/locations across the event.
Then, we discuss the case the strongest shock observed by Solar Orbiter so far, associated with efficient production of very high energy electrons (up to 18 MeV) and protons (up to 30 MeV).
