Image of Comet Christensen
Here is an image of Comet Christensen (C/2006 W3), taken by society member James Abbott on the 18th August this year.
This comet was discovered in November 2006 by Eric Christensen of the Catalina Sky Survey, Tuscon. At the time the comet was located ~8.7 AU from the Sun (approximately the Sun-Saturn distance). The comet reached perihelion at a still quite distant 3.12 AU from the Sun in July this year and, at that time, the comet brightened to around 9th magnitude – visible in many smaller backyard telescopes and even binoculars from dark sites. It is currently magnitude 11 and so one needs very dark skies and a more capable telescope to see it.
