CORONAL HOLE:
A coronal hole on the Sun is turning to face Earth. Coronal holes are places in the sun's atmosphere where the magnetic field opens up and allows solar wind to escape.
Go to Space Weather and view the incredible image.
In the image, magnetic field lines are color-coded. White field lines are closed; they hold the solar wind in. Golden-brown field lines are open; they allow the solar wind out.
A stream of solar wind flowing from this coronal hole is expected to reach Earth on August 24th or 25th. High-latitude sky watchers should be alert for auroras when it arrives.

So if we see an aurora here in Florida tonight we're in trouble yes. I didn't see any last night so we are probably safe.
