A new active region appeared on June 19th, quickly growing in size over two days (June 20-22, 2018). Active regions are areas of enhanced magnetic activity on the Sun's surface, generating the huge loops and dynamic surges observed here. Charged particles spinning along the field lines above the active region are illuminated in this wavelength of extreme ultraviolet light. The superimposed Earth icon gives a sense of just how large these loops are.
