Description
During the extreme solar storm of May 2024, the orbital configuration of solar observing missions offered a rare opportunity to track the full life cycle of the active region where the responsible eruptions originated. Particularly, Solar Orbiter was located near the far side of the Sun—approximately 170 degrees from Earth—allowing continuous monitoring of the source active region before, during, and after facing Earth. This contribution presents remote-sensing observations from Solar Orbiter’s instruments, capturing the evolution of coronal structures, flares, and CMEs. When combined with data from Earth-viewing missions such as SOHO, SDO, and Hinode, this enables near-global coverage of the solar corona and magnetic connectivity.
In addition, we will present in-situ measurements from Solar Orbiter, and compare them with those from Parker Solar Probe and near-Earth spacecraft (including ACE, Wind, and DSCOVR), to analyze the propagation of the associated interplanetary CMEs and solar energetic particles associated to the events. This multipoint dataset provides key insights into the structure and dynamics of the heliospheric disturbances, as well as their magnetic connectivity to the solar source region. The results highlight the value of coordinated observations across the heliosphere to better understand space weather events as system-wide phenomena, from solar origin to planetary impact.
