This weekend the 10th & 11th of August wasn't a moderate geomagnetic storm as we had expected (see previous post Geomagnetic Storm Watch 2013 08 10 11 HD Geomagnetic Storm Watch 2013 08 10 11 HD
) maybe because the CME had missed earth altogether or it hasn't arrived yet.
But we did get a moderate solar flare C8.4 at 21:58
UTC Sunday evening and a more intense flare class M1.5 around Sunspot 1817 in the southern hemisphere. These two solar flares are geoeffective. The M1.5 class created a wave of ionization in the upper atmosphere above Europe and might have hurled a coronal mass ejection toward Earth.
More M class flares and CMEs can be expected from the growing sunspot 1817.
Also more solar wind to inundate the earth's magnetosphere on August 16-17th is from a new gigantic coronal hole.
Thank you for watching and hope to see you again soon :)
