bright white light and luminescent stationary light cloud with green beam((NUFORC Note: US Navy missile launch. PD))We were walking home from dinner when we looking into the sky and saw a bright white light almost resembling a comet and moving pretty slow at an upward diagonal angle. We stopped to watch because it looked so strange, it had a tail of white light coming out which massed into a large white cloud that appeared lit. There are absolutely no clouds in the sky tonight and everywhere around this light mass was empty sky. While the light was on the right of the cloud a thick somewhat translucent green beam was stationary coming out of the left side. The light continued to move upward and to the right and eventually got far enough away that it was no longer connected to the light cloud. When this happened the green beam also dissipated. The light cloud however remained in the sky for the next 10 minutes. The original light moved far away but remained visible, it appeared to move further up in the sky and then there seamed to be another shower like light beam extendi! ng downward. It remained in that position for roughly 5 minutes and then disappeared. We both watched this unfold as well as two other people on the street across from us. There are no missile launches or rocket launches recorded near this area tonight and we are left wondering what we saw.
