C/2013 US10 Catalina – A Christmas Comet

Comet-Catalina2alt-1280-5-750

I last viewed Comet Catalina in August when it was only visible in the southern hemisphere. It is now visible low in the east during the early hours of the morning around 5am, but will be steadily gaining in height throughout December and January. It is currently magnitude 6 and easily seen in 8x or 10x binoculars as a faint grey smudge in the constellation Virgo.

The comet is displaying a couple of really nice, widely separated, tails at the moment with the fainter ion gas tail at the bottom, blown at high speed away from the direction of the Sun by the solar wind. The dust tail at the top is moving much more slowly away from the comet. Having been dislodged from it’s home in the Oort Cloud recently on a hyperbolic trajectory Catalina is making just one approach into the Solar System before vanishing back out and never to be seen again. The comet reached perihelion, it’s closest approach to the Sun, on November 15th and is now on the journey out.
