New comet C/2012 X1 (LINEAR)

C/2012 X1 (LINEAR) was discovered by the LINEAR survey using a 1.0-m f/2.15 reflector from Socorro, NM, USA, on Dec. 08.38. Their automatic routines do not require human intervention, so it was reported as asteroidal and posted in the NEO Confirmation Pageunder the temporary designation CE63887.

Splitting event in comet 168P/Hergenrother

Over the past few weeks, comet 168P/Hergenrother has been under intense scrutiny due to its strange behaviour, namely a 6 magnitude surge in its brightness in a matter of several nights. Simultaneously the central condensation became markedly brighter and sharper, whilst the coma was also seen to grow in size.

New Comet: P/2012 T7 (VOROBJOV)

Cbet nr. 3260, issued on 2012, October 18, announces the discovery of a new comet (discovery magnitude 20.1) by Tomas Vorobjov on three 120-s images that he took on October 15 remotely with Alexander Kostin (Houston, TX, U.S.A.) using a 0.81-m f/7 Ritchey-Chretien reflector located at the Mt. Lemmon SkyCenter via the Sierra Stars Observatory Network. The new comet has been designated P/2012 T7 (VOROBJOV).

Update on Comet 168P/Hergenrother

Our team performed follow-up observations of comet 168P/Hergenrother on 2012, Oct. 22.4, remotely through the 2m, f/10 Ritchey-Chretien + CCD of Faulkes Telescope North (Haleakala) under good seeing conditions, and a scale of 0.3arcsec/px. Comet 168P has recently undergone an outburst with its magnitude increasing from ~14-15 to magnituide ~9.5.

New Comet: P/2012 T1 (PANSTARRS)

Cbet nr. 3252, issued on 2012, October 11, announces the discovery of a new comet (discovery magnitude 20.7) by Pan-STARRS survey on CCD images obtained with the 1.8-m Ritchey-Chretien + CCD on October 06. Prediscovery Pan-STARRS observations from 2011 July 28 were identified by G. V. Williams. The new comet has been designated P/2012 T1 (PANSTARRS).

Updated data for comet C/2012 S1 (ISON)

Our team performed follow-up observations of comet C/2012 S1 (ISON) on 2012, Sept. 28.6, remotely through the 2m, f/10 Ritchey-Chretien + CCD of Faulkes Telescope North (Haleakala) under good seeing conditions, and a scale of 0.3 arcsec/px. After stacking 13 R-filtered exposures, 120-seconds each, comet ISON appears as a pale blob of light, slightly elongated toward the south-west (this is particularly obvious looking at the azimuthal median subtraction rendition).
