Comet C/2009 R1 McNaught is becoming bright(ish)

C/2009 R1 (McNaught) is becoming brighter, and may soon be (just) visible to the unaided eye ... in the northern hemisphere. It's completely unobservable for us Southern hemisphere types, although we may see it late July. There is a good image at Astronomy Post of the Day, and some lovely images of the comet near NGC 891 by Francois Kugel and Michale Jaeger.
