Welcome to the website for the Comet Wirtanen Observing Campaign.
Our intention is to provide a central clearinghouse for basic information regarding comet 46P/Wirtanen (WERE-tuh-nun) and other high profile comets, to encourage and facilitate the acquisition, analysis and interpretation of observations, and to promote collaborations between researchers.
Now that Wirtanen has reached naked eye brightness (at least at dark sites), one popular question is "Where do I need to look to see it?" Because of the close approach, the comet is rapidly moving from South to North and changes its position from day to day. So the best way to figure out where to look is to use our star charts to guide you in using star patterns to find the comet. On the day of close approach, it is only a few degrees from the Pleiades star cluster, which makes a nice pointer.
We've had a lot of images submitted by observers from all over the world. If you have cloudy skies (or just want to see some great pictures), check them out: AOP Wirtanen Gallery. Images are also available at the Spaceweather.com Gallery or at a number of facebook sites.
