Do you see the❓rotate into view in this video of the Sun? This question mark shaped feature that was seen Dec. 21 – 22 is an elongated coronal hole, which are areas of open magnetic field that appear darker in extreme ultraviolet light.
These holes are the source of streaming plasma that we call solar wind. While this exercise is akin to seeing shapes in clouds, it is fun to consider what the sun might be asking? Perhaps what the new year will bring?
