Coronal holes, visible as dark patches in extreme ultraviolet and soft x-ray solar images, indicate cooler, less dense regions with open, unipolar magnetic fields in the solar corona. These areas allow solar wind to escape easily, resulting in fast solar wind streams. They’re more common during solar minimum years and can persist for multiple solar rotations, predominantly at the solar poles. These holes, especially when near the solar equator, can cause geomagnetic storming at Earth, impacting

• Broad Coronal Hole • This was the dominant feature this week on the sun. It was easily recognizable as the dark expanse across the lower half of the sun. Coronal holes are magnetically open areas on the sun that allow high-speed solar wind to gush out into space. They always appear darker in extreme ultraviolet. This movie is generated for a wavelength of 211 Ångstroms (21.1 nanometers) which highlights a spectral line emitted by iron atoms that have lost 13 electrons (also known as iron-14 or

A substantial coronal hole rotated across the face of the sun in footage captured Jan. 30 - Feb. 3, 2017, by NASA’s Solar Dynamics Observatory. Coronal holes are areas of open magnetic field from which solar wind particles stream into space. In this wavelength of extreme ultraviolet light, the coronal hole appears as a dark area near the lower center of the sun. Extreme ultraviolet light is typically invisible to our eyes, but is colorized here in bronze. This same coronal hole was facing Earth

A coronal hole was the single largest feature on our star March 13-15, 2018, stretching out across more than half the Sun’s diameter. Coronal holes, a regular occurrence on the Sun, are areas of open magnetic fields from which solar wind rushes out into space. They appear dark in certain wavelengths of extreme ultraviolet light, like the one captured here by our Solar Dynamics Observatory satellite. Earth is inset for scale, giving a good sense of just how extensive this coronal hole is. https:/

A substantial coronal hole began to rotate into view of our sun observing spacecraft over the past few days. Coronal holes are magnetically open areas of the sun's magnetic field structure that spew streams of high speed solar wind into space.

The most distinctive feature on the Sun from Oct. 31 - Nov. 2 was a good-sized coronal hole nearly centered on the Sun’s face. The coronal hole — which appears as a dark area in this extreme ultraviolet image captured by our Solar Dynamics Observatory — is an area of open magnetic field from which high-speed solar wind rushes out into space. Coronal holes are a common occurrence, and such solar wind can trigger effects like auroras when it interacts with Earth’s magnetic field. https://go.nasa.g
