this was clear looking and had lights in a band all the way around made no sound and felt like electricity

My parents were playing poker with the uncles and aunts in the garage and there was a sudden bright light to the north my uncle seeing this thought someone was in his backyard with a flood light shining.  i was still up with my sister and a few of my cousins and we looked out the window and noticed this object with a bright light coming from this oval thing.  it was about 20 to 30 feet in diameter and was down in the tall grass it was about 8 to 10 feet in height with no apparent windows or a way in the weather was clear you could see the hills in the back ground clearly temp was about 70 deg it had no sound and no smell but had a feeling of electrical like standing under a powerline. when my uncle tried to get close my mother ran into the room and made us all get onto the floor and to stop looking out the window.
we had reported this to the police and they said that they had about 20 reports over the last 30 to 40 minutes. we dont talk about this anymore but i saw what i saw and you cannot take that out of my mind no matter what anyone says.
