Incorporating Magnetic Field Characteristics into EUV-Based Automated Segmentation of Coronal Holes
Jeremy A. Grajeda, Laura E. Boucheron, Michael S. Kirk +3
Coronal holes (CHs) are magnetically open regions that allow hot coronal plasma to escape from the Sun and form the high-speed solar wind. This wind can interact with Earth's magne…

Quantifying the Consistency and Characterizing the Confidence of Coronal Holes Detected by Active Contours without Edges (ACWE)
Jeremy A. Grajeda, Laura E. Boucheron, Michael S. Kirk +2
Coronal Holes (CHs) are regions of open magnetic field lines, resulting in high speed solar wind. Accurate detection of CHs is vital for space weather prediction. This paper presen…

Proposed Resolution to the Solar Open Magnetic Flux Problem
C. Nick Arge, Andrew Leisner, Samantha Wallace +1
The solar magnetic fields emerging from the photosphere into the chromosphere and corona are comprised of a combination of "closed" and "open" fields. The closed magnetic field lin…
