Comet 46P/Wirtanen is magnitude 16.7 and 98 million miles from Earth in this 3 image GIF and is now following Seiichi Yoshida's magnitude curve which could make 46P a faint naked eye comet in December. Comet 46P/Wirtanen is predicted to reach about magnitude 3.5 when it will only be 7 million miles from Earth on December 16 this year and the comet will be 50 degrees above the western horizon when the Moon sets at 8UT/1AM in Denver and over 6 hours will move 1 degree across Earth's night sky on that night. 46P should be brighter than magnitude 6 and visible in the night sky from mid November until mid January.
