On 15th November, D. J. Tholen, University of Hawaii, reported the discovery of an unknown comet in three images taken with the 8.2-m Subaru telescope by himself with C. Trujillo, the comet was first noticed in the images by S. Sheppard. Tholen noted that the static images show a tail extending at least 8″ in position angle 235 deg; however, while blinking the images, it’s possible to see a tail twice as long as that. Magnitude and or size predictions have not been issued anywhere yet but watch this space. Below are the preliminary orbital elements for the comet.
