Comet McNaught has now entered the joint ESA and NASA Solar & Heliospheric Observatory (SOHO)'s field of view, which has been looking at the Sun continuously for over a decade now.
The Sun is in the centre blocked out by a small disc in front of the camera, you can see Mercury to the lower left of the Sun, with Comet McNaught to the left of the image.
They've got an animation (under LASCO/C3) of the passage so far, which really lets you see the solar wind starting to push the tail back. When the comet has moved out of the field of view I'll also put up an animation. The comet should be visible in SOHO until the 15th or 16th. After that people in the southern hemisphere should definitely try and look at this comet.
