The sunspot region is actually a collection of dark blemishes on the surface of the sun that evolved rapidly over the last two days. Sunspots form from shifting magnetic fields at the sun's surface, and are actually cooler than their surrounding solar material.
According to Fox, some of the intense magnetic fields in the sunspot region are pointing in opposite directions, making it ripe for solar activity.
"This is a fairly unstable configuration that scientists know can lead to eruptions of radiation on the sun called solar flares," Fox explained.
The sun is currently in the midst of an active phase of its 11-year solar weather cycle and is expected to reach peak activity sometime this year. The current sun weather cycle is known as Solar Cycle 24.
NASA's Solar Dynamics Observatory launched in 2010 and is just one of a fleet of spacecraft keeping close watch on the sun for signs of solar flares, eruptions and other space weather events.
