Seeing Comet C/2014 Q2 Lovejoy, 5-13 January

Printable black and white horizon chart facing north an hour and a half after sunset showing the location of comet C/2014 Q2 Lovejoy as seen from Adelaide. Similar views will be seen from Southern Hemisphere locations at the equivalent local time.

Over the next few days the Moon leaves the evening sky, and once again comet  C/2014 Q2 Lovejoy has a chance to shine again. Even with full Moon, comet Lovejoy has been easy to see in binoculars.

With the Moon waning and rising later the comet, which is brightening as it heads towards maximum brightness on this Sunday January 11, should now be easily seen as a dimmish fuzzy star with the unaided eye. In binoculars it looks like a large ball of cotton wool and in even small telescopes a thin faint tail can be seen.

For the next 7-8 days the obvious constellations of Orion and Taurus are your guide to finding the comet. The comet is currently around magnitude 4.8, and may get as bright as 4.5 or  hopefully even brighter.

Click to embiggenComet Lovejoy on 29 December 2014, before the rising Moon made it too hard to see. The comet is above Orion and Canis Major. This is a stack of 10x15 second images taken with my Canon IXUS, ASA 400. Click to embiggen.

If you go out when the sky is dark (a little after 10:20 pm daylight saving time in most of Australia), and look north-east you will see the distinctive shape of the "saucepan" almost dead ahead of you.

Just above this is a bright-blue white star, Rigel.

For the next few days if you sweep your eyes (or binoculars) north you will follow a trail of brightish stars, these form the celestial river Eridanus.  After you have passed the fifth star and before the sixth is the space where the comet will pass. There are no bright globular clusters in this area so the comet is distinctive as a fuzzy star to the unaided eye, and a large fuzzy ball in binoculars or telescopes. You may need to locate it in binoculars before you are confident of a visual sighting. If you watch on consecutive days you can see the comet move.

From around the 8th start your sweep at the saucepan it self,  then from the 10th the comet is nestled between the legs of Taurus the Bull. Start your sweep at blue-white Bellatrix, the bright star below and to the north of the  saucepan (not the bright red Betelgeuse below and to the south),  towards the like of stars that marks Orion's shield  and then on further to a U shaped group of faintish stars, just above the obvious inverted "V" that is the head of Taurus. The "U" shape is where the comet will be at its brightest.

Once again, the printable charts above can help you with your quest. For telescope users, the image will be upside down compared to the charts. Remember, when looking for the comet allow at least 5 minutes for your eyes to adjust and become dark adapted. Here's some hints on dark adaption of your eyes. If using the charts above, cover your torch with red cellophane so as to not destroy your night vision.

Good comet hunting!

Hi and thanks .
I went out tonight to see if I could see it but no the moon is too bright. Will try again . I'm in Parafield Gardens.

I could see it from Suburban Largs in 10x 50 binoculars. I did hav to stand where the Moon wasn't in direct view. Over the next few days the Moon will go away and it will be easier to see.

Can't get a view from Vic Park WA. will try again tomorrow or see the live stream:(
