A canyon-like hole has opened in the sun’s atmosphere, and it is spewing a broad stream of solar wind toward Earth. NASA’s Solar Dynamics Observatory is monitoring the structure, shown here on March 13th
This is a “coronal hole”–a region where the sun’s magnetic field opens up and allows solar wind to escape. Coronal holes appear, in various shapes and forms, several times each month. This one is unusually wide, stretching more than 800,000 km across the face of the sun.
NOAA forecasters say there is a 55% chance of G1-class geomagnetic storms when the solar wind stream arrives on March 14th or 15th. G1-class storms are relatively minor and have little effect on satellites and global power grids. However, they can disorient animals that migrate using magnetic cues at high latitudes and usually spark bright auroras around the Arctic Circle
