FAST-GROWING SUNSPOT: In the past few hours, new sunspot AR2924 has more than doubled in size. This movie from NASA's Solar Dynamics Observatory shows its rapid development. Solar flares may be in the offing if the growth continues apace.

FARSIDE SUNSPOTS: NASA's STEREO-A spacecraft is monitoring two ultraviolet hotspots just behind the sun's eastern limb.

These are potentially significant sunspot groups. The regions will rotate into view this weekend.

BIG SOUTHERN SUNSPOT: Two days ago, sunspot AR2924 was barely visible. Now it is a behemoth many times larger than Earth. Eduardo Schaberger Poupeau photographed the fast-growing active region today in Rafaela, Argentina.

So far, the sunspot has not produced any major flares. However, it is developing a mixed magnetic field in which "+" and "-" polarities are in close contact. The stage is set for explosive magnetic reconnection

🌌ARCTIC AURORA WATCH: Arctic auroras are likely on Jan. 9-10 when a minor stream of solar wind is expected to hit Earth. The gaseous material is flowing from a southern hole in the sun's atmosphere.
