Observed a oval shaped ufo which was a green translucent color. it moved from the west and stopped very abruptly in a field to the left off the road we were traveling on. as we drove closer to its location it disappeared and it left a tracer that didn't linger. the whole experience may not have lasted more than 3 seconds. as we came to the hill maybe a qtr of a mile ahead the sky opens up just a little and i thought i saw an additional tracer. it was like seeing a flash of light as the object moved ne. i don't have any evidence of this occurrence but i can provide the location. it was only a mile from my home.
