Around the end of this week Comet Lulin (C/2007 N3) will hopefully be visible to the naked eye (or at least with binoculars).

It should be down near Saturn (I think if you follow the opposite side of the Plough/Big Dipper to the one you use to find the North Star down you should hit Saturn) and if you follow the line made by Betelgeuse and Bellatrix (the top two stars of Orion) across to the left that’ll be where it ends up towards the end of the weekend.
