Reporting
No major meteor showers occurNo major meteor showers occur in September, but you probably saw a stray meteor/fireball, which can occur on any night. (On September 8, 2013, there were reports of fireballs in Oregon and California, USA.) Meteors can burn with different colors, from orange-yellow, yellow, and red, to blue, green, or violet. This depends on the metals in the meteor, and which atoms/molecules in the atmosphere it hits. A meteor's tail (called a train, or wake) can last about 1 to 10 seconds. Sometimes, a bright fireball can leave a persistent train that lasts a few minutes to over 30 minutes. Factors that affect the speed of a meteor in the atmosphere include its size, its initial speed, and the angle when it hits the atmosphere.
