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 254000 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 QHYCCD camera models, we had to change some of the currently used camera type keys.
Comet 67P/Churyumov-Gerasimenko has its own far-ultraviolet aurora, data reveal. It is the first time such electromagnetic emissions in the far-ultraviolet have been documented on a celestial object other than a planet or moon.
CBET 4885 & MPEC 2020-S119, issued on 2020, September 20, announce the discovery of a comet (magnitude ~18.5) by Nicolas Erasmus (South African Astronomical Observatory), in four 30-s CCD images taken in 5" seeing on Sept. 17.6 UT with a 0.5-m f/2 Schmidt reflector at Mauna Loa, Hawaii, in the course of the "Asteroid Terrestrial-Impact Last Alert System" (ATLAS) search program. The new comet has been designated C/2020 S3 (Erasmus).
A permeable heart with a hardened facade –the resting place of Rosetta’s lander on comet 67P/Churyumov-Gerasimenko is revealing more about the interior of the 'rubber duck' shaped-body looping around the Sun.
Whether it’s a surprise asteroid, colorful aurora or a heart-stopping eclipse, the landscape of the night sky is constantly changing. When a new visitor appears in view, it’s guaranteed to grab the attention of professional astronomers and casual sky gazers alike. Well, consider the Hubble Space Telescope the paparazzi of the sky, as it’s managed to snap the closest images yet of the sky’s latest visitor to make headlines, comet C/2020 F3 (NEOWISE), after it passed by the Sun. Comet NEOWISE is considered the brightest comet visible from the Northern Hemisphere since 1997’s Hale-Bopp. It’s estimated to be traveling at a whopping 40 miles per second, or 144,000 miles per hour. The comet’s closest approach to the Sun took place on July 3 and it’s now heading back to the outer parts of the solar system, not to pass through again for another 7,000 years or so.
CBET 4822 & MPEC 2020-P10, issued on 2020, August 02, announce the discovery of a comet (magnitude ~18) by Leonardo S. Amaral (Rio de Janeiro, Brazil) on three 60-s CCD exposures taken on July 23 with a 0.3-m f/4 reflector. The new comet has been designated C/2020 O2 (Amaral).
