Several images of Asteroid Florence at it's close approach to Earth in the early Denver morning of 1 September 2017 when it was about 4.4 Million Miles from Earth. The 2.7 mile wide asteroid was about magnitude 8.7 moving at almost 1/2 degree per hour across the night skies of Denver. These images were taken through holes in a mostly cloudy sky.
