Comet C/2014 Q2 (Lovejoy)

August 16, 2015 Leave a comment

Comet C/2014 Q2 put on a superb show at perihelion (closest approach to the Sun) in mid January 2015 and I caught some images of it back in March 2015  when it was around magnitude 6.8. It is fading fast now as it leaves the Solar System, but can still be picked up in telescopes at magnitude 10.3. Here you can just make it out as a fuzzy ball of light at the centre of the image passing through space between the constellations of Draco and Bootes.

Discovered by R.A. Kowalski and the Catalina Sky Survey in October 2013 C/2013 US10 is now at magnitude 7.5 and brightening. It is only observable in the southern hemisphere at the moment, but should be visible in the north from November. This photo shows the bright nucleus, the ion tail to the left and the finer dust tail rising vertically in the photo.
