A bright green fireball was spotted by hundreds of people in southern Pennsylvania on Tuesday and eight other states in the night sky.

In addition to Pennsylvania, the fireball was reported from Delaware, Maryland, New Jersey, North Carolina, South Carolina, Virginia, Washington DC, and West Virginia.
"In the atmosphere of the earth occur several thousand meteors the size of a fireball every day," said the AMS. "However, most of them occur over the oceans and uninhabited regions, and many are masked by daylight. Those who perform at night have little chance of being detected due to the relatively small numbers of people they notice.
"The brighter the fireball is, the rarer the event. As a rule of thumb, each exponential decay decreases by about one-third for each size class that gradually becomes lighter. Experienced observers can only see about 1
Another fireball was spotted just before midnight Tuesday over Germany. This traveled from southeast to northwest and ended above Hamburg.
