I took a look and at first thought is was a helicopter, but the sound was way off, not the normal thudding but deep bass buzzing sound the lights were wrong as well. The lights were green with very bright white light that was much brighter than I could look at. I grabbed my camera and snapped the following sequence before it shot off towards the south (look at what the light did to my image sensor), the images are shaky as I had to put it on 1 second exposure (well the camera did that for me) as it was dark. I wanted to capture the image in context with the surrounding for you guys to look at. These images were shot in raw and the full exif data is attached to each image.
