TigerNut writes: CBC is running a story on the upcoming closest approach of Comet Catalina. While the headline makes it sound like a one-night deal for the morning of January 1, the best viewing may actually occur next weekend (Jan 8-10) because the moon will not be a bright distraction at that time. The CBC reports: "Comet Catalina, which is less than 20 kilometres across, was discovered in 2013 by the Tuscon, Ariz.-based Catalina Sky Survey, which looks for potentially hazardous near-Earth objects. At first, it was thought to be a very large near-Earth asteroid. But astronomers soon realized it was actually a very long, near-parabolic orbit and observations with the Canada-France-Hawaii telescope showed 'modest cometary activity.'"
