Modifies a noun

• ejection: The sun is blocked out by a solid disk in front of the camera, making it possible to image the coronal mass ejection.

• flux: Clearly the observed solar coronal hole surface flux provides a good description of the observed stellar minimum X-ray surface flux.

• plasma: The spatial distribution of the coronal plasma resembles very much the typical magnetic field topology expected for the Sun.

• hole: Well, coronal holes are the source of most of the solar wind found in space.

• loop: Coronal loops are found in active regions, around sunspots.

• discharge: This is a fiery entity whose brilliance is not great enough to blind us to its coronal discharge under normal viewing conditions.
