A very pretty object. 6th magnitude and "near the moon?" 6th magnitude makes it very bright. And the Moon is new. That's why this is a very easy binocular comet at the moment, and can be imaged with just a few minutes of total exposure time. |

Whatever happened to the days when I could walk outside my urban home and look up to see a huge comet, 17P/Holmes clear as day in 4th magnitude skies? http://cometography.com/pcomets/017p.html According to the rough chronology of bright comets, we are due one. |

When the sky is dark enough on New Year's Eve it's only 5 degrees high. At the moment it's only above the horizon in daylight. |

The article was only about New Year's Eve... when it's still pretty close to the Sun, though bright enough to be a good binocular object for many, and there's no moon intereference. There will be better opportunities in January and February, and the comet will probably be brighter then, as well. |
