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 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 251000 comet observations of more than 1300 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.

The observable region is an approximate indication of the latitude at which the comet may be seen. The period when visible is calculated for latitude 45°N and 45°S.
In order to unify the camera type abbreviation keys of all ZWO ASI camera models, we had to change some of the currently used camera type keys.
On June 15, 2020, a citizen scientist spotted a never-before-seen comet in data from the Solar and Heliospheric Observatory, or SOHO -- the 4,000th comet discovery in the spacecraft's 25-year history.
CBET 4790 & MPEC 2020-L09, issued on 2020, June 02, announce the discovery of a comet (magnitude ~20) in four 45-s w-band CCD images obtained with the Pan-STARRS1 1.8-m Ritchey-Chretien reflector at Haleakala. The new comet has been designated C/2020 K7 (PANSTARRS).
ESA's Solar Orbiter will cross through the tails of Comet ATLAS during the next few days. Although the recently launched spacecraft was not due to be taking science data at this time, mission experts have worked to ensure that the four most relevant instruments will be switched on during the unique encounter.
CBET 4782 & MPEC 2020-K159, issued on 2020, May 25, announce the discovery of a comet (magnitude ~18) by G. J. Leonard on images taken on May 22 UT with the Catalina Sky Survey's 0.68-m Schmidt reflector. The new comet has been designated C/2020 K3 (Leonard).
CBET 4775 & MPEC 2020-J68, issued on 2020, May 14, announce that an apparently asteroidal object discovered on images taken at Palomar on 2019 June 4 and 7 with the 1.2-m f/2.4 Schmidt telescope (and given the minor-planet designation 2019 LM_4 when published on MPS 1001527, along with observations made elsewhere on June 8) has been re-discovered showing cometary appearance at two other observatories. The new comet has been designated P/2019 LM4 (Palomar).
