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.
