At approximately 0050 local time I was looking out my kitchen window which faces in he direction of the western sky. The sky condition were mostly clear with only a few widely scattered clouds that were being illuminated by the moon's light.I was puzzled why my exterior motion lighting had illuminated and tried to override the automatic function and reset the exterior lights to off. Approximately 30 seconds after I reset the exterior lights they came back on and almost immediately I witnessed an an intense blue colored light that increased in intensity quickly and had the appearance of lightning in its flashing behavior. It appeared to be located at a direction of approximately 330 deg (compass coordinates relative to my position) and the movement appeared to be approximately a west to east direction at a rapid speed. The intensity of the light was such that the mountains and sky to the west, which includes the Sandwich range and Mount Chocorua also illuminated. Furthermore, the lighting and flashing also had the appearance of a meteor/fireball entry. Video surveillance of the time of incident, indicates a series of flashes increasing in intensity. The shadows created by the trees and reflected off several surfaces from the intense blue light are visible and indicate relative movement in a west to east direction. Additionally, the surveillance video also shows the western sky illuminating and making a mountain to the west visible.
