Neon Green Stealth like sphere with pulsating lights, witnessed by 2 adults and a child.May 24th, around 9:30pm, I was sitting outside on my front patio. The sun was just begining to set. My Neighbor's daughter was playing two doors down and something in my head had told me to look up towards the horizon. I'm in a partially vegitated area with large trees, so if I were to just lok in that direction, trying to look for a specific object, chances are that I would not have been able to spot what I saw.I was smoking a cigarette at that time, and as I said, "Something in my brain had told me to focus in that specific direction as if I was being told so." As I looked up, my neighbor's child said, at the same time I saw it and said, "Mommy! Mommy! Mommy, come here quick! Look at pretty green light in the sky! What is it?" She came out and immediately started to panic and thats when I said, "Am I really Seeing this? Am I crazy or are you seeing this too!" There was a very bright, pulsating chartruess spherical object, moving at a high speed, and very low altitude. It was a very bright neon like color sphere and it made not one sound. I cannot tell you how big it was but, it was literally pulsating with light. At first I thought it was an airplane since I live just down the road about 10 miles from a small airport. The name of the airportis, Hillsboro Aviation. (So if you need to call them to see if they picked up anything on radar, you have te name.) When it went over us, there was absolutely zero sound. I even tuned into background noise to make sure there was a jet exhaust sound. Absolutely zero noise! And the strange thing was, being so close to an airport, theres constant air traffic. When this approached, there was not one aircraft in the sky. So we would have heard it. I ran out to the to a clearing and watched it continue from it going northbound. I contined observe to se if I could make out any form of object. It immediately came to a hault in mid air. By that time, it was very close to the airport and then it began to flash and get brighter. It sat there for a good two minutes. At that time, I decided to make a run for my phone to snap a shot. As I came back out and was fumbling with my camera, I looked up, and it made slight turn and began to move, then it took off at a blink of an eye. This is the second time I've seen these spheres. I've seen blue ones in the Tillamook National Forest coming home from Salmon fishing. And they were in the forest, then bolted out into a meadow. They moved so fast that the trees swayed as they exited the forest and were spinning around the sky, then disapeared into orbit.
