Description

We utilized various analysis methods to study a coronal mass ejection (CME) observed by SOHO’s LASCO on March 23, 2024, at 01:25 UT. The shock wave's radio signature in the metric range was detected by Callisto stations ALASKA-COHOE and Australia-ASSA, and the STEREO/SWAVES instrument recorded the interplanetary counterpart. Additionally, we gathered Interplanetary Scintillation (IPS) observations from the Low Frequency Array (LOFAR) and the Mexican Array Radio Telescope (MEXART). The UCSD team produced 3D reconstructions of heliospheric density, complemented by STEREO-A observations. We estimated the solar wind speed using IPS data and analyzed the radial velocity of the coronal shock through spectral analysis of type II bursts. In this study, we present our findings on the velocity and trajectory of the CME/shock system, as well as the effectiveness of various analysis techniques in tracking the CME/shock evolution from the Sun to 1 AU.
