Terry Lovejoy
Terry Lovejoy (born 20 November 1966) is an information technologist from Thornlands, Queensland, Australia, most widely known as an amateur astronomer. He has discovered six comets, including C/2011 W3 (Lovejoy), the first Kreutz Sungrazing comet discovered by ground-based observation in over 40 years. He is also known for popularizing procedures for modifying consumer-grade digital cameras so that they can be used for digital camera astrophotography. Astrophotography Lovejoy is known among amateur astronomers for identifying modifications to digital cameras needed for astrophotography. Such cameras come configured with built-in filters that cut off infrared light. They also cut off some of the red light that many deep space objects emit. After he published procedures to modify those filters, many amateur astronomers were able to improve their deep space photography. Gordon J. Garradd named 61342 Lovejoy in honor of Lovejoy after discovering it on August 3, 2000. O ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C/2007 K5 (Lovejoy)
The following list is of comets with very long orbital periods, defined as between 200 and 1000 years. These comets come from the Kuiper belt and scattered disk, beyond the orbit of Pluto, with possible origins in the Oort cloud for many. For comets with an orbital period of over 1000 years, see the List of near-parabolic comets. See also * List of comets by type * List of hyperbolic comets * List of periodic comets Periodic comets (also known as short-period comets) are comets with orbital periods of less than 200 years or that have been observed during more than a single perihelion passage (e.g. 153P/Ikeya–Zhang).

C/2007 E2 (Lovejoy)
C/2007 E2 (Lovejoy) is a non-periodic comet discovered by Terry Lovejoy on 15 March 2007. Its perihelion was 27 March 2007, while its closest approach to Earth was 25 April 2007 in Hercules at a distance of 0.44 AU. Maximum apparent magnitude was approximately +8. The discovery was made using a Canon EOS 350D consumer grade digital camera, and not a CCD survey camera.

C/2011 W3 (Lovejoy)
Comet Lovejoy, formally designated C/2011 W3 (Lovejoy), is a long-period comet and Kreutz sungrazer. It was discovered in November 2011 by Australian amateur astronomer Terry Lovejoy. The comet's perihelion took it through the Sun's corona on 16 December 2011, after which it emerged intact, though greatly impacted by the event. As Comet Lovejoy was announced on the 16th anniversary of the SOHO satellite's launch it became known as "The Great Birthday Comet of 2011", and because it was visible from Earth during the Christmas holiday it was also nicknamed "The Great Christmas Comet of 2011". Discovery Comet Lovejoy was discovered on 27 November 2011 by Terry Lovejoy of Thornlands, Queensland, during a comet survey using a Schmidt–Cassegrain telescope and a QHY9 CCD camera. It is the third comet discovered by Terry Lovejoy. He reported that it was "a rapidly moving fuzzy object" of 13th magnitude, and additional observations were made by him over the next couple of nig ...

C/2013 R1 (Lovejoy)
C/2013 R1 (Lovejoy) is a long-period comet discovered on 7 September 2013 by Terry Lovejoy using a Schmidt–Cassegrain telescope. It is the fourth comet discovered by Terry Lovejoy. C/2013 R1 crossed the celestial equator on 14 October 2013, becoming a better Northern Hemisphere object. History By 1 November 2013, the comet was visible to the naked eye near the Beehive Cluster (M44), about halfway between Jupiter and Regulus. It became more impressive than comet ISON. In binoculars, the comet has the appearance of a green, unresolved globular cluster. C/2013 R1 made its closest approach to Earth on 19 November 2013 at a distance of , and reached an apparent magnitude of about 4.5. On 27 November 2013 the comet was in the constellation of Canes Venatici, near the bottom of the handle of the Big Dipper. From 28 November until 4 December 2013, the comet was in the constellation Boötes. On 1 December 2013 it passed the star Beta Boötis. From 4 December until 12 December 2013 ...
