Butterfly-Shaped Coronal Hole Emerges in the Sun
• A large, butterfly-shaped coronal hole has emerged on the sun, emitting fast solar wind towards Earth.
• The approaching equinox increases Earth's susceptibility to geomagnetic storms caused by solar wind.
• Geomagnetic storms can disrupt technology and trigger auroras; sky watchers should stay alert.
Large coronal hole emits fast solar wind
A fascinating phenomenon has been observed on the sun: a large, butterfly-shaped coronal hole. This dark region, now positioned to potentially impact Earth, is emitting fast solar wind. While the sun has been relatively quiet in terms of solar flares, with only minor C and B flares recorded, the emergence of this significant coronal hole warrants attention.
