Comet Lovejoy (C/2013 R1) now within small telescope range

This year is turning out to be a bumper year for comets. We have already seen two naked eye comets in PanSTARRS (C/2011 L4) and Comet Lemmon (C/2012 F6), with much anticipated ISON (C/2012 S1) still to hit its best as it heads towards next month's perihelion.

To add to the mix periodic comet Encke (2P/Encke) is currently visible in the morning skies. Although not naked eye, Encke should reach binocular magnitude during November. In addition, one more recently discovered comet could also soon hit the fringe of naked eye brightness; its name comet Lovejoy (C/2013 R1).

Discovery

Australian Terry Lovejoy, an information technologist and amateur astronomer discovered the comet on September 7, 2013. He imaged it at mag. +14.4 with a digital camera attached to his 200mm (8-inch) Schmidt-Cassegrain telescope.

Incredibly, this is the fourth comet discovered by Lovejoy in the space of just 6 years. One previous discovery of particular note was C/2011 W3 (Lovejoy), the first Kreutz Sungrazing comet discovered by ground-based observation for more than 40 years.

Location, magnitude and star chart

Comet Lovejoy is a well-placed early morning object during October from both the Northern and Southern Hemispheres. It remains in good condition for Northern Hemisphere observers for the remainder of the year and well into 2014. However, those located in the Southern Hemisphere aren't so lucky; Lovejoy won't be observable from mid-November to early February.

The comet started October moving at a leisurely pace through Monoceros before crossing the constellation border into Canis Minor on October 17th. During this time it brightened by over a magnitude (from +10.3 to +9.0) and to within small telescope range. The comet could also be glimpsed with large 20x80 binoculars although remained beyond the reach of popular 10x50 binoculars. However that will hopefully change soon, Lovejoy is predicted to reach magnitude +5.9 by the end of November.

On October 26th, Lovejoy passes less than a degree north of first magnitude star Procyon (α CMi - mag. +0.34). It remains in Canis Minor until October 30th, before passing into Cancer. On November 7th, Lovejoy is located just south of M44 "the Praesepe" open cluster. It then moves briefly into Leo from November 11th to November 14th. On the 14th, Lovejoy should be at about magnitude +6.3 and an easy small telescope and binocular object.
