Abstract: The solar wind is an intriguing phenomenon that influences the heliosphere and has direct implications on the Sun-Earth environment called “Space Weather”. Generally, the solar wind is classified into two types: the fast solar wind originating from open-magnetic field regions (Coronal Holes) and the slow solar wind associated with different sources at the Sun. These source regions may correspond to the large-scale coronal features observed by the Extreme Ultraviolet Imager/Full Sun Imager (EUI/FSI) onboard Solar Orbiter. Using high-resolution observations from EUI/HRI and coordinated observations from PROBA-2/SWAP, STEREO-A/EUVI, SDO/AIA, and EUI/FSI enables us to pinpoint their footpoints location. We also use back mapping of the slow solar wind observed at 1AU to its corresponding source regions. In addition to that, we perform a detailed analysis of the in-situ solar wind parameters to distinguish between different types of solar wind and their source regions.
