On the night of August 31, I imaged the asteroid Florence which made a relatively close pass of Earth. At a distance of 4.4 million miles, it is one of the larger near Earth asteroids. With a size of 2.7 miles, any collision would not be good news, but luckily no collisions are forecast for the foreseeable future. It won't come this close again until after the year 2500.

Radar observations indicate it has two small moons in orbit around it.
