Modeling CME encounters at Parker Solar Probe with OSPREI: Dependence on photospheric and coronal conditions

Context: Coronal mass ejections (CMEs) are eruptions of plasma from the Sun that travel through interplanetary space and may encounter Earth. CMEs often enclose a magnetic flux rope (MFR), orientation which largely determines CME's geoeffectiveness. Current operational CME models do not model MFRs, but number research ones do, including Open Solar Physics Rapid Ensemble Information (OSPREI) model. Aims: We report sensitivity OSPREI to range user-selected photospheric coronal conditions. Methods: four separate observed in situ by Parker Probe (PSP). vary input conditions using magnetograms (HMI Synchronic, HMI Synoptic, GONG Synoptic Zero-Point Corrected, ADAPT). To field reconstruction, we employ Potential-Field Source-Surface (PFSS) its source-surface height 1.5--3.0 R$_{\odot}$ with 0.1 increments. Results: find both magnetogram PFSS source surface affect evolution as it propagates Sun's corona into space, therefore accuracy MFR prediction compared in-situ data at PSP. There is no obvious best combination height. Conclusions: The moderately sensitive Based on where region located Sun, there be practices when selecting an use.
