Here's the standard image from GEOS -
NASA's Solar Dynamics Observatory is monitoring a dark rift in the sun's atmosphere. The spacecraft's Atmospheric Imaging Assembly (AIA) took this extreme ultraviolet picture just hours ago
It's a "coronal hole," a vast region where the sun's magnetic field has opened up and allowed the solar wind to escape. Indeed, a solar wind stream flowing from this hole is heading toward Earth, due to arrive on June 7th or 8th. High latitude sky watchers should be alert for auroras on those dates.
