The following article from http://spaceweather.com indicates strong solar wind on August 16th and 17th. The Auroras should be astounding.
SOLAR WIND, INCOMING: A long, narrow hole has opened in the sun's atmosphere, and it is spewing high-speed solar wind into space. NASA's Solar Dynamics Observatory photographed the fissure on Aug. 13th pointing directly at Earth:
This is a "coronal hole"--a region where the sun's magnetic field opens up and allows gaseous material to escape. Solar wind emerging from the hole is expected to reach Earth on Aug. 16th and 17th.
The incoming stream of solar wind may be preceded by a CIR (co-rotating interaction region). CIRs are transition zones between slow- and fast-moving solar wind. They often contain shock-like density gradients and strong magnetic fields that do a good job sparking auroras. And because Arctic aurora season began just a few days ago, the aurora photo gallery may soon receive some new additions.
