The extraterrestrial rock is tumbling through space alongside thousands of similar objects in our solar systems main asteroid belt, roughly between the orbits of Mars and Jupiter.
S. Larson reports that images of the main-belt minor planet (596) show the object to be in apparent outburst with a comet-like appearance.
A new feature has been added to COBS analysis page enabling the observer to filter the observation data by observation type.
A. Boattini reports his discovery of a faint comet with a moderately diffuse coma that is 6"-7" wide and a central condensation that is about 3"-4" in size on four 30-s co-added CCD exposures taken with the Mt. Lemmon 1.5-m reflector in Arizona.
This morning EPOXI, the spacecraft formerly known as Deep Impact, flew within 435 miles (700 km) of the nucleus of Comet 103P/Hartley 2. Images taken during the encounter are being downloaded from the spacecraft throughout the day. A few of the images have been released by the EPOXI team and can be found here.
S. Nakano, Sumoto, Japan, reports the visual discovery of a comet independently by Kaoru Ikeya ...
Under the scope of CARA project, comet 103P/Hartley is continuously monitored by a group of dedicated observers, using small and medium size remote telescopes, now available worldwide.
Comet 103P/Hartley is currently in the middle of Auriga moving to the southeast at a little over 3° per day. With closest approach to Earth on Oct. 20 (0.121 AU) and closest approach to the Sun on Oct. 28 (1.059 AU), the comet is as big and bright as it will probably get for this return. Unfortunately, the bright Full Moon will make observing the comet difficult for the next week and a half.
Richard Wainscoat reports the discovery of a comet with a coma diameter of approximately 4" on 45-s CCD images taken with the 1.8-m Ritchey-Chretien "Pan- STARRS 1" telescope (+ W filter; bandpass 400-700 nm) at Haleakala.
J. V. Scotti, Lunar and Planetary Laboratory, University of Arizona, reports his recovery of comet P/2000 Y3 on images obtained with the 0.9-m Spacewatch reflector at Kitt Peak.
