POLAR CROWN CORONAL HOLE: A large hole in the sun’s atmosphere has formed around the sun’s north pole. This is called a “polar crown coronal hole,” and it is spewing solar wind into space. This image, based on data from NASA’s Solar Dynamics Observatory, shows where the sun’s magnetic field has opened up, allowing the gaseous material to escape.
Although this hole is not directly facing Earth, forecasters believe that some of the emerging solar wind could spill down and brush against our planet’s magnetic field on Feb. 4th and 5th. Minor geomagnetic storms and Arctic auroras are possible when the solar wind arrives later this weekend.
