Geomagnetic storming levels back to normal

Geomagnetic storming reached the G2 (Moderate) level at high latitudes again early today. Bright auroras could be seen around Arctic Circle. It was sparked by one of two coronal mass ejections observed on September 2.  Solar radiation storm levels have returned to

The large sunspot cluster 1319 harboring energy for solar flares

Active region 1319 contains many individual sunspots. The swarm is growing. Over the weekend, the sunspot group's total area nearly tripled as shown in this movie from the Solar Dynamics Observatory:
