We are still awaiting the arrival of two coronal mass ejections launched by a couple of M-class solar flares from sunspot region 2975. Geomagnetic storm conditions up to the moderate G2 level is expected with even a slight chance of strong G3 storm conditions being possible according to the NOAA SWPC. The impact is expected within the next 3 to 12 hours. But that is not today's headline story actually. Sunspot region 2975 yet again steals the spotlight as it just erupted with a major X1.3 solar flare.
