Solar Power - Magnetic Energy

Last July 6th a major BLAST in the Sun released a pent-up magnetic energy which triggered the recent auroras seen in some regions of our globe.

If the jettisoned particles come from the part of the sun facing Earth at that moment, they're more likely to reach our atmosphere.
The tumultuous solar storm sparked on July 6 brought about a radio blackout, geomagnetic storms, and of course, auroras. from here

According to the latest status update from ESA's Space Weather team: The CME (Coronal Mass Ejection) has not arrived at Earth. However, we can see some increase in the solar wind speed and dynamic pressure. The flow of protons from the Sun is increasing, which is an indication that the CME is on its way.

Some moderate to strong geomagnetic storm maybe expected, starting this evening. 
And there could be some rather nice Northern Lights tonight..!
