Comet C/2014 Q2 Lovejoy, 20th and 23rd of December
Comet C/2014 Q2 Lovejoy continues to delight observers, with a partial tail disconnection event and some impressive tail twisting.
In binoculars it is an easy catch, and in my Canon point and shoot images it has significantly brightened. I made it out to be magnitude 5.8, other estimates have been around 5.6-5.7. Well into the unaided eye range under dark skies.
I have extended my comparison of the comets tail out to three days, the images are 5x180 second luminance images Bin 2 taken with iTelescope T12 stacked in ImageJ on the comet and a MEDIAN Z project taken then inverted. North is to the top.
Resolution is 3.5 arc-secs/pixel
