Decaying Active Region 1944 erupted impulsive M1.3 solar flare at 21:51 UTC on January 13, 2014. This active region is about to rotate onto the west limb. Active Region 1946 is also about to rotate behind the west limb. Other five visible regions remain stable.

Meanwhile, a stream of solar wind is buffeting Earth's magnetic field. Minor geomagnetic activity is being observed due to a high speed solar wind stream. The density of the stream remains low, so it's not causing strong geomagnetic storms.
