Solar origins of a strong stealth CME detected by Solar Orbiter

Aims.We aim to locate the origin of a stealth coronal mass ejection (CME) detected in situ by MAG instrument on board Solar Orbiter, and make connections between CME observed at Sun, interplanetary (ICME) measured situ. Methods. Remote sensing data are analysed using advanced image processing techniques identify source region CME, global magnetic field time eruption is examined Potential Field Source Surface (PFSS) models. The observations Sun compared with Orbiter spacecraft, plasma properties Wind spacecraft. Results. found be quiet cavity northern hemisphere. We find that has strong situ, despite originating from an extremely weak field. Conclusions. interaction ICME its surrounding environment likely cause higher strength Stealth CMEs require multi-wavelength multi-viewpoint order confidently region, however their elusive signatures still pose many problems for space weather forecasting. findings have implications observing sequences instruments such as EUI designed capture
