Comet Lovejoy (C2014/Q2), the fifth comet to be discovered by Australian amateur astronomer Terry Lovejoy on August 17, 2014, has now brightened sufficiently to move with binocular range. As it continues to increase in brightness, it should soon be visible to the naked eye and is expected to peak at about magnitude +4.5 during the middle of January.
Since the comet is located quite far south of the celestial equator it's well placed for observation from southern and tropical latitudes during December. For those located at northern temperate latitudes it's not visible until the second half of the month but after that it's observable in excellent condition.
Location and star chart
Comet Lovejoy starts December in the constellation of Puppis moving in a northwesterly direction. It then passes into Columba on December 17th where it remains until December 27th before crossing the border into Lepus. The comet is expected during this time to increase from magnitude +7.6 to +5.2 and therefore move from binocular to naked eye range.
Over the next few months it will be very interesting to follow Lovejoy as it's already a couple of magnitudes brighter than originally predicted and could brighten even further still. As with all comets, they are extremely unpredictable objects where anything can happen - and often does - so keep watching!!
