Seemed like an enermous asteroid entering Earth.I was driving my car talking to my friend, when all around us seemed to glow a pale green colour. I looked at my friend to comment, when i seen in the sky a quick, bright flash high up in the sky. Then what seemed like a comet, but inside the atmoshphere, shooting down towards the distant horizon, then its tail of light following. It took about 1/2 a sec to reach the horizon from the flash in the sky, which i presume was its entrance into the Earth`s atmosphere. I was travelling East, with the asteroid/whatever to my 10 o`clock. The green sky faded as i watched the asteroid plummet to Earth. I have reported this with the local authorities, whom are now investigating.
