Object appeared above neighborhood. I estimate it was about 1/2 mile away and completely silent. The flight path was heading east in the northeast sky and was hardly straight moving approximately 70 MPH. It's path was jagged (straight line, but many sudden small redirections). The light was bright. in the photos, the ambient light is given by a corner street lamp. The UFO light was bright enough to appear in the picture, even though the street lamp was flooding the picture with light.At the end of the 1.5 minute event, the light grew dim and then it ascended at a speed of approx. 300+ MPH.Living near an air force base, I see military craft often. This was unlike anything I have seen before. Being unable to identify the object, by the strictest definition, this was a UFO.
