According to NOAA's Space Weather Center, on Wednesday night, the solar flare from the sun will hit Earth. There is nothing to fear from the sunstorm; the only problem is fluctuations in the potentially weak electricity grid.
However a fun side effect would be the aurora borealis activity.
Obviously, you need a clear sky to see the northern lights. It is better to see solar activity in a dark sky; this means that light pollution and luminosity of the moon may limit the aurora's ability to see.
Aurora borealis are created by electrically charged particles from the sun that strike the earth and collide with the atmosphere. The collision produces energy that creates the light that makes the aurora visible.
