Comet Observation database (COBS) saw first light in 2010 and is maintained by Crni Vrh Observatory. It is a free and unique service for comet observers worldwide which allows submission, display and analysis of comet data in a single location.
Amateur astronomers can make valuable contributions to comet science by observing comets and submitting their observations to COBS as professional astronomers typically do not have telescope time required to acquire regular observations. We therefore encourage comet observers worldwide to submit their observations and contribute to the COBS database.
Registered observers may submit observations using a web based form which stores the observations in an SQL database and stores them in ICQ format. Observations may be queried and plotted in the web site or exported for further processing, analysis and publication. The database currently contains more than 266200 comet observations of more than 1520 different comets and represents the largest available database of comet observations.
The data stored in COBS is freely available to everyone who honors our data usage policy. Please cite COBS as the reference if you use it for comet studies.

CBET 5134 & MPEC 2022-L97, issued on 2022, June 13, announce that an apparently asteroidal object discovered on June 4 with the 0.68-m Schmidt reflector of the Catalina Sky Survey has been found to show cometary appearance by CCD astrometrists elsewhere after the Minor Planet Center posted it to the PCCP webpage on the basis of a comet-like orbit. The new comet has been designated C/2022 L1 (Catalina).
Astronomers using a fleet of world leading telescopes on the ground and in space have captured images of a periodic rocky near-Sun comet breaking apart. This is the first time such a comet has been caught in the act of disintegrating and could help explain the scarcity of such periodic near-Sun comets.
ESA’s Comet Interceptor mission to visit a pristine comet or other interstellar object just starting its journey into the inner Solar System has been ‘adopted’ this week; the study phase is complete and, following selection of the spacecraft prime contractor, work will soon begin to build the mission.
