I work as a security officer and while I was working I was walking from one building to another and as I was looking up I saw nothing in the sky and then all of a sudden I saw this big white bluish bright ball enter the sky and it got brighter and brighter and bigger and bigger for about 2 to 5 seconds behind the ball there was a fiery type spark trail behind it kind of like when a campfire crackles and then everything was gone. it disappeared as quickly as it came in. It was one of the coolest things I've ever seen.
