Activity has picked up today. Active region 2443 developed a delta spot and was responsible for a series of flares including a C7.9 flare and a two C5 flares. Throughout the day, these size of these flares steadily increased. The chart shows the each flare that happened in the day. The width of the bar shows the flare duration and the height of the bar shows the intensity.
Keep an eye on this region as it rotates into the Earth strike zone. If it continues the current pattern, it could produce an M-class flare in the next day or two.
Geomagnetic activity increased to KP-3 and produced some magnificent aurora storms in iceland late in the period. Here’s a tweet that Sigurdur William (@SiggiPhoto) posted from iceland:
