Asteroid Florence

An asteroid this large has not whizzed past the Earth in over 100 years.

Sky and Telescope is providing updated finder charts as it moves up the Milky Way. This object is a challenge to track down and, given the full Moon, you will probably need at least a six-inch telescope to see it. An all-sky chart, binoculars, and an advanced star atlas would aid your search.

Also, note the links S&T has included for live viewing over the Internet.

Radio telescopes have been tracking the asteroid during this close approach, and have just discovered two moons orbiting around it:

I have attached two photos that I took using an eight-inch Schmidt Cassegrain - from the morning of September 4 - showing its motion over a period of six minutes.
