Changing light from bright to dim, to off to blue/redLooked out my window to see if I could catch the meteor shower. Saw a helicopter heading east. Noticed extremely bright light to my right. It was hovering. Light dimmed. Started to move west, then east. Light became bright again and then seemed to vanish. I then saw red and blue lights seeming to circle it. It moved further east. It hovered back and forth. Bright light came back, it dimmed. It headed to the airport and landed. I've been hearing helicopters since.
