Abstract
It is well known that flare-accelerated electrons can produce hard X-ray (HXR) emission and Type-III radio bursts. The HXR emission is produced by the accelerated electrons propagating towards the chromosphere where they deposit their energy. In contrast, Type-III radio bursts are produced by the accelerated electron beams traveling toward the outer solar atmosphere. Hence a temporal correlation between these two kinds of emission may imply a common origin of the accelerated electrons providing insight into the acceleration process, and allowing us to connect electrons at the Sun to those in the heliosphere 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 an excellent time resolution of 0.5 s. Simultaneously there were observations of multiple coronal and interplanetary Type-III radio bursts from several instruments such as WIND/WAVES, I-LOFAR, and ORFEES spanning the frequency range from 1 - 1000 MHz.We find an excellent temporal correlation between the X-ray and radio time series. We do multiwavelength imaging analysis using AIA, STIX, and NRH to locate the acceleration origin and track the electron beams during the eruption.
