- These gaps, located at the Sun's poles, are called coronal holes.
- It has long been known to the astronomical community that the fast solar wind comes from coronal holes.
- Areas on the surface of the Sun called coronal holes, where the magnetic field is quite open and highly energetic charged particles stream out and hit the earth's magnetic field and interact with it.
- Stepping out by a distance equivalent to the solar radius, the coronal brightness drops by about a factor of a thousand, to be about a billionth that of the solar disk.
2Anatomy
Relating to the crown of the head. 〔天文〕（与）（日）冕（有关）的；（日）晕的 3Anatomy

- A coronal CT image is the preferred initial procedure.
- Axial views and images were reoriented into coronal and sagittal views.
- Particularly in tumors of the superior sulcus or the lung base, images in the coronal or sagittal plane can be used to demonstrate the relationship of the tumor within the lung apex to adjacent structures.
- Sagittal and coronal cross-sectional images afford the best views and will be used throughout the MRI portion of pelvic anatomy.
