C/2006 P1, also known as Comet McNaught, is a non-periodic comet that was discovered on August 7, 2006 in Australia by Robert H. McNaught.
Comet McNaught first became visible to the naked eye in early January, 2007. It was viewable as a magnitude -3 comet in the northern hemisphere near Venus, until January 13, 2007.

Image data: 5 exposures 1/20 sec at f/2.8 and ISO 100 combined.

Due to its proximity to the sun it had a short window for viewing, and could only be spotted during twilight.
The comet passed SOHO LASCO C3's field of view from January 12 - 15, and quickly became brighter than any other comet since 40 years.
