If the Sun is down and you are in the northern hemisphere, look at the finder chart here and then go outside and look at this object. Now. This website will still be here when you get back.

Hi there. Have a good time?

No one quite knows what happened. This normally bland, boring, not visible without a fairly large telescope comet suddenly decided to flare into something that can be seen from big cities.

Personally, I can’t wait to see the science on this one.  One of the best collections of data I’ve seen so far is here. There is an annulus of material (from an outburst? from a tail seen face on? from both?), jets, and evidence of molecular carbon in the tail. Why? No idea.

Go look again :-)  Will discuss this more when the science papers start coming out.


  1. Thank you! I’ve been counting on you to help me sort this out. It’s been exciting to look at this from downtown San Jose, and to watch it change over the past several nights. Looking forward to the discussion!

  2. What about in the Southern Hemisphere?

  3. I have taken a few timelapse movies of the comet over the past few days and am out every night that i can until its not visible anymore. its easy to get photos of this one.
