A green oval shaped orb with a small red light at the bottom hoovering over a tree lined cattle pasture.On Monday, May 17, 2016, around 4:30am in Houston, Texas, I was headed home, traveling westbound on Airport Blvd. between Cullen Blvd and Scott St. It was raining lightly at the time. To my left there was a narrow strip of tree lined pasture where cattle graze. Rising above the trees was a oval shaped green orb that was about 10-15 ft. wide. At the bottom of the orb was a small red light. The orb was moving back and forth over the trees. Since I was the only one traveling on that stretch of the road, I dropped my speed to about 5mph. I also rolled down my driver side window to get a better look. I noted that there was no sound and no blinking lights coming from the orb, which made me realize that it was not a helicopter and definitely not an airplane. I traveled down to the road to a break in the median and made a u-turn heading back towards the ufo. That’s when it started flying off to the east, increased in speed and disappeared.
