At the height of each magnetic flip, the sun goes through periods of more solar activity, during which there are more sunspots, and more eruptive events such as solar flares and coronal mass ejections, or CMEs. By the end of the movie, the flip is almost complete. Over the next 16 years, each set of lines is seen to creep toward the opposite pole. The visualization shows how in 1997, the sun shows the positive polarity on the top, and the negative polarity on the bottom. The entire sun's magnetic polarity, flips approximately every 11 years – though sometimes it takes quite a bit longer – and defines what's known as the solar cycle. Additional gray lines represent areas of local magnetic variation. The field lines swarm with activity: The magenta lines show where the sun's overall field is negative and the green lines show where it is positive. This visualization shows the position of the sun's magnetic fields from January 1997 to December 2013. Watch this video on the NASA Goddard YouTube channel.
