Comet Observation database (COBS) was developed in 2010 and is maintained by Crni Vrh Observatory. It is a unique service offering comet observers to submit, display and analyse comet data in a single location and is opened to comet observers worldwide. Registered observers may submit the observations using a simple web-based form which will store their observations into an SQL database and display them in ICQ format.
Data stored in COBS database is freely available to everyone with respect to our data usage policy, and can be analysed with COBS online tools or exported and further used in other analysis software and publications.
Database currently contains more than 225000 comet observations of more than 1100 different comets and represents the largest available database of comet observations.
Amateur comet observers can make a useful contribution to science by observing comets and submitting their observations to the COBS, as the professional astronomers do not have the time nor the telescopes needed to gather such data. We encourage comet observers worldwide to submit their observations and contribute to the COBS database.

When the Rosetta spacecraft successfully touched down on comet 67P/Churyumov-Gerasimenko on September 30, 2016, the news was shared globally via Twitter in dozens of languages. Citizens the world over were engaged by the astronomical achievement, and now experts are eager to learn as much as possible about the critically important celestial body of ice.
We were saddened to learn the news yesterday that Klim Churyumov, who discovered Rosetta's comet together with Svetlana Gerasimenko in 1969, has passed away.
It’s been several years that a new method of processing CCD observations was announced by german astronomer Uwe Pilz. The method was a promising way for amateur astronomers, to generate a visual equivalent magnitude using a CCD measures with a very simple way of processing. Now after several years, there were several observers which were using this method, one of most active was Kevin Hills from United Kingdom. The huge amount of his observations made possible a deep comparative analysis of this method with visual and classic CCD magnitudes.
During the last month of Rosetta's operations at Comet 67P/Churyumov-Gerasimenko, it was no longer possible to observe the comet with telescopes on Earth because it was not far from the Sun's position in the sky and therefore not visible in the night-time. Fortunately, NASA's Kepler space observatory stepped in, taking images of the comet every 30 minutes from 7 to 20 September, providing important context to Rosetta's in situ measurements.
