See Comet Catalina pass overhead from UK when closest to Earth

Having brushed by bright star Arcturus on 1 January, Comet Catalina (C/2013 US10) continues its trek through the constellations of the far north. Now a circumpolar object for the British Isles, in the early hours of 17 January it lies between famous double star Mizar (ζ Ursae Majoris) and the Pinwheel Galaxy (M101), virtually overhead in the UK.

Discovered on 31 October 2013 by the Catalina Sky Survey, C/2013 US10 is an Oort Cloud comet making its first foray into the inner solar system. Currently dashing northward through the constellation Boötes, Comet Catalina passes within ½ degree of Arcturus, the brightest star of the northern sky, on the morning of 1 January 2016.

Comet Catalina (C/2013 US10) is currently a morning object in Virgo low in the southeast before dawn twilight for UK observers. The comet has a photogenic close encounter with Venus and the waning crescent Moon on the mornings of 7—8 December, then rapidly heads north through the constellation Boötes for a closer brush with Arcturus on New Year’s Day.
