Travelers In The Night

My Catalina Sky Survey Teammate Brian Africano discovered his 4th comet while asteroid hunting in the constellation of Ursa Major with our Schmidt telescope on Mt. Bigelow, Arizona. Observers with small telescopes equipped with electronic cameras are able to track Brian's 4th comet as it comes to near the orbit of Mars before it retreats into the cold dark region of our solar system not to return until 3000 AD.
