Wed, 11 Mar 2015 - Seen Comet Lovejoy?


 For more images see the Gallery below

Comet 2014 Q2 Lovejoy, discovered last August by prolific comet-hunter Terry Lovejoy, remains easily observable using binoculars and small telescopes. It is now about sixth magnitude and is observable all night in Cassiopeia, though it is highest during the early evening.

Observing from Morpeth, Northumberland, Alastair McBeath reported that on 3 March 'The rounded, misty coma still seems roughly 0.25° across to me, and although I could follow the straight tail for about half a degree northeast from the coma's middle on March 1-2, that seemed much less obvious, although I was struggling to pick up even some of the nearby seventh magnitude stars in the washed-out sky then. My impression was the coma was plausibly in the magnitude +5.9 to +6.2 range (mag +6.0 or fainter more recently). Fading, but not yet quite gone!'

During March the comet fades as it gets farther from Earth. It reached perihelion – its closest to the Sun – on 30 January. 

To find it, use the sky map here for the sky looking north-west at about 8 pm from the UK. Look high up for the well-known W-shaped constellation of Cassiopeia. Though the comet is bright enough to be found without too much searching with binoculars as it gets fainter you may need a more detailed map, showing fainter stars, which you can get by clicking on the map below. The more detailed map is black on white to make it easier to print out.

To obtain actual positions (an ephemeris), suitable for setting Go To telescopes, go to the SPA/BAA Comet Section page. In the blue section at the bottom, scroll down and click on Comet Ephemerides, then choose Comet Lovejoy.

SPA Forum member MeteorB took the image from near Kilwinning, Ayrshire and 'had to aggressively stretch the image to get a decent impression of the tail. 'The picture is in mono to hide very poor colour balance due to hideous light pollution.' Click to enlarge
