Hi Duncan,
This comet is really close to the Sun in the sky so even if it does get bright it will be hard to find. It is currently very low in the morning sky in Leo but will soon move to very low in the evening sky as it approaches perihelion.
There was some discussion of it in the forum and on the comet section mailing list here:

and there are plenty of images in our archive here:
