A nearly square coronal hole was one of the noticeable features on the Sun this past week. A coronal hole is an area from which high-speed solar wind streams into space. It appears dark in extreme ultraviolet light because there is less material in that region emitting those wavelengths. Inside the coronal hole you can see bright loops where the hot plasma outlines small bits of the solar magnetic field sticking above the surface. Since this hole is so far south on the Sun, there is less chance that its solar wind stream will strike the Earth.

Saw tthe headline and immediately thought, “I am Coronal-Holio!”
“Are you threatening me?”
“The streets will flow with the blood of the nonbelievers!”
Mentioned this to a neighbor, and he asked how big of a beanbag he’d need to play cornhole with the sun.
Cincinnati — the city were sharing a three-way and a round of cornhole is a family evening.
