The Watchers – Impulsive M3.9 solar flare off the eastern limb

May 10, 2013

 

There are currently 8 numbered active regions on the visible side of the Sun. Sunspot 1734 is now located in the southwest quadrant and is crackling with C-class flares. Sunspots 1732, 1734 and 1736 are each rotating towards the southwest limb and will all be out of direct Earth view May 12, 2013. Meanwhile, three new regions rotated into view off the east limb and were numbered 1742, 1743 and 1744. Regions 1740 and 1741 continued to decay and are now spotless plages.
