Welcome to COBS!
Between 1989-1997 an intensive comet photometry program at Crni Vrh Observatory resulted in contribution of hundreds of CCD observations to the ICQ database and IAU Circulars. This also created a need for an online observational database. The first version was created in 2002 and was used by Slovenian comet observers. The database contained 35 visually observed comets during the period 2002-2008. The best observed comets, with complete light-curves collected have been C/2002 C1 (Ikeya-Zhang), C/2002 V1 (NEAT), C/2001 Q4 (NEAT) and C/2004 Q2 (Machholz) as well as outburst of comet 17P/Holmes in late 2007.
The Comet Observation Database (COBS) is unique service, offering comet observers to submit, display and analyse comet data in a single location. It is maintained by the Crni Vrh Observatory and is opened to comet observers worldwide. Registered observers may now submit the observations using a simple web-based form which will store their observations into an SQL database and display them in ICQ format. Furthermore the users will be able to create light-curve graphs of selected comets and see all the observations. We encourage comet observers worldwide to submit their observations and contribute to the COBS database.
Observers are reminded that the ultimate address which is collecting and storing comet data is International Comet Quarterly.

New Comet: C/2014 E2 (JACQUES)
Cbet nr. 3828, issued on 2014, March 14, announces the discovery of a comet on CCD images taken by C. Jacques, E. Pimentel and J. Barros using a 0.45-m f/2.9 reflector at the SONEAR Observatory near Oliveira, Brazil. The new comet has been designated C/2014 E2 (JACQUES).

Rare form of nitrogen detected in comet ISON
Astronomers observed the Comet ISON during its bright outburst in the middle of November 2013. Subaru Telescope's High Dispersion Spectrograph has detected two rare forms of nitrogen in the comet ISON. Their results support the hypothesis that there were two distinct reservoirs of nitrogen the massive, dense cloud ("solar nebula") from which our Solar System may have formed and evolved.

NASA Preparing for 2014 Comet Watch at Mars
This spring, NASA will be paying cautious attention to a comet that could put on a barnstorming show at Mars on Oct. 19, 2014. On that date, comet 2013 A1 Siding Spring will buzz Mars about 10 times closer than any identified comet has ever flown past Earth.
