September Starts with Flare(s)


The Solar Dynamics Observatory satellite keeps continuous watch on the Sun. It’s spotted several flares so far this month. The X9.3 flare was the strongest flare yet during the current solar cycle, the roughly 11-year-cycle during which the Sun’s activity waxes and wanes. The current cycle began in December, 2008, and is now decreasing in intensity and heading toward a solar minimum.

A Couple of Solar Flares


A large active region on the Sun has rotated into view over last few days and is giving off warning signs that this could be the source of powerful solar storms. It has already fired off two small flares that were observed by the Solar Dynamics Observatory on 2 January and shown here in a wavelength of extreme ultraviolet light.
