Coronal hole faces Earth
A coronal hole is facing our planet today. While this coronal hole is poorly defined in the sense that there is not one large opening, we do see several openings (dark areas) which combined cover a significant portion of the Sun's northern hemisphere. We even see an opening near the equator that has already passed the central meridian.
