Signatures of localised particle acceleration at a global coronal shock wave.

Abstract
Extreme ultraviolet (EUV) waves are global waves in the solar corona which can accelerate particles. The efficiency of this acceleration depends on local plasma characteristics such as the Alfvén speed and the geometry of the magnetic field. This shock-driven particle acceleration can produce radio signatures such as Type II radio bursts and herringbone emission. Aims. Here we investigate signatures of particle acceleration by a weak coronal shock on 10 March 2024. In particular, we combine EUV images with radio imaging and spectral observations to determine how and where this weak shock could accelerate energetic particles.
