Tomorrow night (Sunday), from 11 PM (EST) till dawn, the Perseids meteor shower shall be occurring. It is supposed to be an amazing sight because there is a new moon that night so there will be no moonlight to distort it.
Some viewing tips/facts:
-Look in the direction where the sky is the darkest
-If you have a very dark sky, you should see a meteor per minute
-Meteors will also occur the following days
