Well as a newbie I have no idea what all this is on about.  I'd like to see this object so can someone help with some points of reference?

That's if it ever stops raining.

Yeah, we need to get rid of the clouds first.

Top chart is a white-stars-on-black which gives a slightly enhhanced idea of what the sky should actually look like. Second chart is a more conventional star map. "2P" marks the position of the comet.

Ah maybe I should have said a complete newbie, however there seems to be a Y shaped constellation (Sagitta) on the maps so I think its turn left towards Sagitta from the bottom of Vulpecula.  

If you could let me know is thats right it would be great.  Also how bright is it at the moment and do we have a tail yet?
 

Whitters

Chris,
Yes thats right. though this baby is moving quickly, at the weekend it was next to the veil nebula in Cygnus. Give it a couple of weeks and it will be gone from our skies. Probably about the same time it stops raining!
tail status: Titchy.
