Spearmint colored object flys extremely fast in the sky then dissappears completely leaving only green trailAt approximately 9:30pm ET while driving home from shopping on RT1 in Revere MA, a friend an I both saw what seemed to be a spearmint green ball of very vivid bright light appear in front of us in the sky then in the only way I can explain it get brighter then moved quickly leaving a light green trail behind it. The instance was only for a matter of seconds but very visible and clear. The two of us exclaimed "what was that"! I can only compare it to a green shooting star yet in the atmosphere and much larger. I came home and began to look up what the occurrance could have been with no luck. Nothing fit the color and the way it appeared then sped irregularly fast then was gone.
