About this work
The only active region observed this week appeared on Dec. 5, 2018 and grew into an average size display of dynamic activity (Dec. 6-7, 2018). As viewed in a wavelength of extreme ultraviolet light, the region presented numerous magnetic loops of charged particles, rapidly changing their shapes and directions. As the sun is approaching its minimum level of activity in its 11 year solar cycle, we expect to see fewer and fewer active regions for quite a while.
