Have you heard? We are now officially in the solar maximum phase! That means we’re in the part of the 11-year solar cycle where solar eruptions, geomagnetic storms, and auroras are most likely to occur. But how do scientists tell where we are in the solar cycle? They count sunspots! Those dark solar splotches tell a story: As solar activity waxes and wanes, so does the sunspot count. But don’t just take our word for it – try it yourself!

On Oct. 24-25, our Solar Dynamics Observatory satellite watched as a solar prominence rose up above the Sun’s surface, twisted around, then became elongated and broke away from the Sun. Prominences are relatively cool clouds of solar material (called plasma) that are tethered above the Sun’s surface by magnetic forces. Although tiny on the scale of the Sun, this prominence stretched out about ten times the diameter of Earth — see Earth inset for scale. These images were taken in a wavelength of

The Sun’s only visible active region sputtered and spurted and eventually unleashed a small solar flare on Feb. 7, captured here by our Solar Dynamics Observatory satellite. The flare appears as a brief, bright flash about midway through the half-day-long clip. Normally, a flare this small might not catch much attention, but solar activity is increasingly rare as the Sun is slowly approaching solar minimum, a natural low point in its 11-year activity cycle. These images were taken in a wavelengt
