New active region produced strong M5.5 solar flare
A new Active Region off the northeastern limb is really active and is crackling with M-class solar flares. Latest strong solar flare, reaching M5.5, occurred at 01:02 UTC on August 18. It did not produce Earth-directed CME.
New active region is numbered as 1547 and it turns toward Earth in days ahead; giving the conditions by now, it could strongly affect our geomagnetic field in the coming days. NOAA/SWPC estimate that there is 20% chance for more M-class events in the next 24 hours.
