During a solar flare, accelerated electrons propagate upwards and downwards from the energy release site along magnetic field lines and produce type III bursts and hard X-ray (HXR) emission. Sometimes, we have simultaneous observations of HXR flux with many peaks and multiple type III bursts in radio emission at decimetric and metric wavelengths. The temporal correlation between these two kinds of emission suggest that the electrons producing these emissions have the same acceleration origin. The multiple HXR fine structures and radio bursts are thought to be signatures of several fragmented energy releases during solar flares. On 2022-Nov-11 11:30 - 12:00 UT, the Spectrometer Telescope for Imaging X-rays (STIX) on Solar Orbiter observed a highly energetic flare event with several fine HXR structures. Simultaneously there were observations of multiple coronal and interplanetary type III radio bursts from several radio instruments. By investigating the evolution of X-ray, extreme ultraviolet, and radio sources, we studied the trajectories of the flare-accelerated electrons in the lower solar atmosphere to understand the characteristics of the flare acceleration process and propagation of accelerated electron beams in the solar corona.
