The sun erupted with a double prominence eruption over a four hour period on November 16th. The eruptions were captured in the 304 Angstrom wavelength of extreme ultraviolet light. It is possible that the second event occurred because of a disruption in the Sun’s magnetic field. The two events happening so close together is why scientists believe this is the case.

A solar prominence is a large wave pushing outward from the Sun’s surface, normally in a looplike pattern. They are full of plasma that has cooled, which allows us to view them. A typical prominence pushes out over thousands of miles. Prominences can also last from a few days or even a few months.
