FAST-GROWING SUNSPOT: Two days ago, sunspot AR1723 did not exist. Now it sprawls nearly 100,000 km (8 Earth-diameters) across the sun's southern hemisphere. NASA's Solar Dynamics Observatory is monitoring the sunspot's rapid expansion:
AR1723 has a 'beta-gamma' magnetic field that harbors energy for M-class solar flares. If the magnetic field is changing as quickly as the underlying sunspot, it could become unstable and explode. Stay tuned for updates, as Earth would be in the line of fire. Solar flare alerts: text, voice.
