I witnessed an enormous, bright lime/acid green parallelogram shaped light/craft drop across the sky. there seemed to be a dark (black) center, with some pinpricks of silver light near the perimeter of the light/craft. it fell from the north/east towards the south, and was extremely close and extremely large and extremely fast in its descent. there was no light trail, no sound, no change in the color of the light. was in my direct eyesight for maybe half a second.
