Two strong M-class solar flares

Signs of life from everybody's favorite star: our very own Sun. It 
produced two strong (R2-moderate) M-class solar flares today!

That is where the good news ends. While it is of course nice to see our 
Sun produce strong solar flares, both the M7.9 solar flare that peaked 
at 09:49 UTC and the M6.2 solar flare that peaked at 15:59 UTC came from 
sunspot region 3098. This sunspot region is currently close to the west 
limb and will soon rotate out of view. A case of too little too late. 
Both solar flare were also rather impulsive (short duration) and the 
M7.9 solar flare did not launch a coronal mass ejection. The M6.2 solar 
flare that peaked just before we published this article will likely also 
not launch a coronal mass ejection. Not a big loss as any resulting 
plasma cloud would likely not have been aimed at Earth anyway.

The remaining sunspot regions on the earth-facing solar disk are 
unremarkable and unlikely to produce M or X-class solar flares. We could 
see the arrival of a weak to moderate coronal hole solar wind stream 
within the next 24 hours but geomagnetic storming is not to be expected. 
Space weather will be relatively quiet in the foreseeable future.
