Looked like a bright green shooting star, much larger, longer tail and brighter than a SS, headed in dowward direction.Last night traveling home on Highway 183 North my friend and I saw out the front windshield what could be described as a "bright green shooting star." It was different from a SS because it was mush larger and it was a lime-green color of light. The diameter of the head of the SS was about 10 times larger than your regular SS. It traveled in a downward direction toward the ground although it was still very high up. It also had a longer brighter tail than a SS. The color can best be described as a very bright lime green light almost neon in color. It was about as long as 6 full moons lined up in a row. This is the second time I have seen this, once about 7 days ago in the southwestern direction from Austin. It was the same description also headed down towards the earth. How far away it was is hard to judge but it did not appear to be in outer space, more likely in the earths atmosphere. It was very noticeable because it was so very bright and green. It was very bea! utiful and unusual. What it was I have no idea though.
