July 11 2012 Fast Moving Solar Wind Impacting Earth's Magnetosphere HD

  
Best viewed with expanded window.
Solar wind from Coronal Hole reached our magnetosphere today. Geomagnetic Storm Expected.
Look up for auroras
We are also still receiving the solar wind from the M and C flares hurled towards earth.

Big sunspot AR1520 has been relatively quiet for the past 24 hours, but this could be the calm before the storm. The sunspot has a delta-class magnetic field that harbors energy for X-class solar flares.
Thank you for watching and have a wonderful week
