NASA's SDO Sees Two Coronal Holes on the Sun

Caption

A pair of substantial coronal holes were the most notable features on the Sun over the past week (March 28-April 2, 2015). These are magnetically open areas out of which solar wind streams. This stream of solar wind from the elongated coronal hole (which has been facing towards Earth) should be reaching Earth about April 2-3 and will likely trigger aurora in the northern latitudes. The images were taken in a wavelength of extreme ultraviolet light.
