Analysis of the Solar Activity - 8 September 2014

Solar activity remains at low levels (C-class solar flares only) since the M1.1 solar flare that occured two days ago. Can we still expect strong solar flares from sunspot regions 2157 or 2158?

Analysis of the past 24h

Both sunspot regions still have magnetic delta structures but solar activity remains rather low especially when you consider the regions currently on the earth-facing solar disk.

We begin with sunspot region 2157 which was the source of a couple of low-level M-class solar flares. This region remained stable but there are spots growing just south of region 2157. These new spots look to be a new sunspot region but they might be included in 2157. Two small delta spots remain present in it's trailing section and an M-class flare remains possible.

Sunspot region 2158 is very quiet but also remains a threat for a moderate to strong solar flare. While it is not very compact it does remain relativly stable with an easily identifiable Beta-Delta magnetic layout. This might be a sleeping giant: M-class activity can not be excluded from this region.

What can we expect in the upcoming 24h?

Both regions 2157 and 2158 keep their magnetic delta layouts. An isolated M-class event from either region can not be excluded.

M-class flare probability: 30% chance
X-class flare probability: 10% chance

Any mentioned solar flare in this article has a scaling factor applied by the Space Weather Prediction Center (SWPC), the reported solar flares are 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.
