Comet 46P/Wirtanen

8 Dec. 2018

On this evening, about a week before closest approach to us (16 Dec,), Comet 46P is visible in binoculars and photos, but as not much more than a fuzzy ball (no tail). Light clouds and numerous satellites (probably mostly geosynchronous) are also visible in this time-lapse sequence spanning 27 minutes. A higher magnification view can be seen here.
