There is a new comet in the early morning sky that can be seen before dawn. Comet 2013 US10 (Catalina) has travelled an estimated one million years from the distant Oort Cloud and will pass the one and only time through our solar system. Closest approach to Earth is on January 12, 2016. Once it’s gone it will never return. It should be a naked eye object towards the end of December as seen from dark locations and away from light pollution. Binoculars and even better, a telescope will show the green glow of the comet’s nucleus.
There is a finder chart on Gary Boyle's website: www.wondersofastronomy.com
