we saw and heard something that isn't explainable.We were sitting in the backyard, in an enclosed porch. We first noticed some lights in the sky at 23:00hrs. When we looked at it through binoculars you couldn't make out the shape but you could see red, yellow, blue and green lights flashing on the object. At 00:00 we noticed another one in the vicinty. By 01:00 we counted 6. 5 of them were in a cluster to the NW, the other one was alone in the NNE. We saw a plane fly in the direction of the one in the NNE, it was much closer than the others, as the plane was getting closer it shot straight up in the sky. At 02:00 I saw a yellow flash of light at the front of the house, at the same moment my sister saw a blue flash of light in the back of the house. At 03:00 we heard a sudden noise in the backyard. It was like a vocal noise but you couldn't understand what was being said. At that point in time we ran into the house and locked the doors and closed all blinds. We then ran to my truck and sat there until my Aunt and Uncle came home. They then checked the backyard and nothing was there.((NUFORC Note: We suspect a twinkling star. PD))
