I came out my front door and saw a red circle shaped light. it was quite large, maybe 4 feet diameter. the center appeared to be darker, while the edges were more diffused. there was no light projected (ie like a flashlight or searchlight). it did not illuminate the area. i could not see thru it to the trees behind it. i looked down to step off my porch and when i looked up it was gone. i looked around and up but there was no longer there.
