Bright blue, white egg shaped light flying very fast and low from right to left of my sight for 2 seconds in Sutton coldfied England.

I saw a bright blue white egg shaped object flying above houses, with no sound, no trail, traveling at speed faster than a helcopter, slower than a shooting star. The last time I saw something flying almost as fast was a Harrier Jet (their base was not far away from my brothers house and it was nothing out of the ordinary for him) flying at night above a small village. The sighting of whatever I saw happened when I was coming home from dancing lessons I had just turned off the Birmingham Road and was traveling at about twenty miles per hour up a very steep hill( Do not know the name of the road but can find out) the weather conditions were cold with a completly clear sky with no moon. I do not know the direction it was going but it appeared in my sight line at about 1 o'clock and disappeared at about 10 o'clock, or right to left. (it is hard to tell the hieght but it was low). The size was about three times biger than the stars in the plow.
