My companion and I witnessed a very bright, large, green ball which shot quickly behind the tree line.I went outside at around 23:00 to have a cigarette with a friend whom is visiting from another state. I live in a very rural area, very wooded and with no close neighbors. The night was clear and many stars were visible as usual.We sat outside for twenty minutes or so to watch the skies. I should note that in the past few weeks, I have witnessed some odd objects in the sky above my house, and thus we were looking for such. The lights we have seen lately are usually red in color, round or triangle shaped, and move too quickly to be stars. My companion and I noticed a couple of these, but as they have become so common, we were not particularly entranced. However, as we gazed to the East, we both saw a very large, VERY bright, green ball of light, which quickly shot above the tree line, in an Easterly direction. Once behind the tree line, the forest seemed to light up with a greenish glow for a couple seconds, then become dark again.The object appeared to be close, though I cannot say for sure, as I was not sure the size or speed. Shortly after, we both heard the whir of what sounded like helicopters, though we did not see any. My cell phone battery also drained shortly after.Prior to this event, a few weeks ago, I tried to film one of the red lights in the sky with my cell phone camera. The quality is very bad, and all I seemed to film was a glowing rectangle that looked nothing like the red light. I should have filed two report I suppose, but the moving red lights were witnessed by at least three other people.
