A stationary light grew in brightness and then dimmed until it was not visible in the daytime sky.A small bright dot that was in the area of where the north star is located from Columbia Falls. It was during the mid-day on a very clear day. The light resembled the size of a planet although it was not inline with the path traveled by the visible planets that are out this month. The light was stationary for several minutes and then got very bright and then slowly dimmed until it was not visible. It never moved from the location where we first saw it. I thought we had just witnessed a supernova.
