Cbet nr.2812, issued on 2011, September 09, announces the discovery of a new comet (discovery magnitude 18.9) by Artyom Novichonok on on six images taken during Sept. 7.02-7.05 UT using a 0.4-m Jigit telescope at the TAU station of the Ka-Dar Observatory (located near Nizhniy Arkhyz, Russia). The new comet has been designated P/2011 R3 (NOVICHONOK).
Cbet nr.2811, issued on 2011, September 07, announces the discovery of a new comet (discovery magnitude 18.7) by Larry Denneau and Richard Wainscoat on two i-band Pan-STARRS images taken with the 1.8-m Pan-STARRS 1 telescope at Haleakala on September 4.5, 2011. The new comet has been designated P/2011 R2 (PANSTARRS).
MPECs 2011-P25, 2011-P37 and CBET 2798 detailed the discovery and follow-up about a secondary nuclear condensation (component B) of comet 213P/Van Ness. Recently we performed some additional follow-up on it, in order to check its evolution.
C/2011 Q1 (PANSTARRS) was discovered on 2011, Aug. 20.44 by PANSTARRS team with a 1.8-m f/4 reflector + CCD from Haleakala, Hawaii, USA. Richard Wainscoat, Marco Micheli, Henry Hsieh and Larry Denneau described it as having a FWHM of 1.2 arcsec while stars have 1.0 arcsec.
Often, comets are portrayed as harbingers of gloom and doom in movies and on television, but most pose no threat to Earth. Comet Elenin, the latest comet to visit our inner solar system, is no exception. Elenin will pass about 22 million miles (35 million kilometers) from Earth during its closest approach on Oct. 16, 2011.
BBC Television in collaboration with Faulkes Telescope and LCOGT today imaged C/2009 P1. The images have been taken with the 2.0 meters Faulkes Telescope North by D. O Briain, BBC Television presenter. The BBC were allocated time on FT North (F65) as part of a new Citizen Science project.
Cbet nr.2779, issued on 2011, August 05, announces the discovery of a new comet (discovery magnitude 18.5) by R. H. McNaught on CCD images taken with the 0.5-m Uppsala Schmidt telescope at Siding Spring on August 1.7, 2011. The new comet has been designated P/2011 P1 (McNaught).
Today, during our observing session with Faulkes Telescope North we observed a fragmentation event in comet 213P/Van Ness.
NASAs EPOXI spacecraft came within 450 miles of Comet Hartley 2, a small comet not even a mile in diameter, which takes about six and a half years to orbit the sun. Designated officially as 103P/Hartley 2, the comet thus became the fifth for which scientists have collected close-up images.
Cbet nr.2768, issued on 2011, July 19, announces the discovery of a new comet (discovery magnitude 19.5) by L. Elenin and I. Molotov on four 240-s unfiltered CCD exposures taken remotely with a 0.45-m f/2.8 astrograph at the ISON-NM observatory near Mayhill, NM, USA, on July 7.3 UT.
