This image was acquired on 2013 November 7. The tail of the comet extends into the open star cluster variously known as the M44, the "Beehive Cluster," and "Praesepe," the latter being Latin for manger. Discovery Terry Lovejoy (Thornlands, Queensland, Australia) discovered this comet on images acquired during 2013 September 7 and September 8, using his 20-cm reflector and a CCD camera. The comet was found as a result of a regular survey Lovejoy conducts to search for new comets. On the six initial images acquired by Lovejoy, the comet's magnitude was given as 14.3-14.8. ![]() Copyright © 2013 by Terry Lovejoy (Stixendorf, Austria)
These are the three discovery images acquired by Lovejoy on 2013 September 7.7. Each exposure was 14 seconds in length and 8.5 minutes separated each image. The first observers to independently confirm the comet were Ernesto Guido and Nick Howes (Remanzacco Observatory, Italy), who first photographed the comet on September 7.7 while remotely using the 32-cm reflector and a CCD camera at iTelescope (Siding Spring Observatory, Australia). They gave the magnitude as 15.5-15.8. In addition, Guido and Howes noted a "sharp central condensation surrounded by a coma about 25" in diameter," as well as a tail extending about 40" toward PA 245 degrees. Early Orbit Calculations The first orbit was published on Minor Planet Electronic Circular 2013-R72, published on 2013 September 9. Using 49 positions spanning September 7-9, Gareth V. Williams calculated a parabolic orbit with a perihelion date of 2013 December 25.79 and a perihelion distance of 0.877 AU.
