Disappearing strobing spiraling lights that split into two lights!A blue light appeared west of white swan slightly above the hill ridgeline. It would get very bright, then dissapear. It came back a green color, got bright again, and dissapeared once again. It reappeared yellow, split into two, and they began spiraling clockwise. They formed back into one, and disappeared.At times it pulsed and gave off an enormous amount of light. It was also in front of the clouds. It eventually lowered in the clouds before the light disappeared.My girlfriend and niece were frightened by it and ran into the house and started crying. Ive never seen anything like it.
