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…

Magnetic Field-Constrained Ensemble Image Segmentation of Coronal Holes in Chromospheric Observations
Jaime A. Landeros, Michael S. Kirk, C. Nick Arge +5
Coronal Holes (CHs) are large-scale, low-density regions in the solar atmosphere which may expel high-speed solar wind streams that incite hazardous, geomagnetic storms. Coronal an…

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…
