M1.1 solar flare from sunspot region 2157
Saturday, 6 September 2014 19:32 UTC
It took a little while but sunspot region 2157 produced it's second strong solar flare since rotating onto the earth-facing solar disk. It was the source of an M1.1 solar flare at 17:09 UTC.
Sunspot region 2157 is not yet in a great position for any CMEs to be earth-directed but that will change in the coming days as it rotates towards the center of the Earth-facing solar disk.
A quick look at sunspot region 2157 and 2158 reveals that both of these regions have magnetic delta layouts and more M-class flaring from either region is possible in the coming days, with a slight chance of an isolated X-class event.
