Dear colleagues,
I am informing you that the first release of Halley - Electronic Catalogue of Comets is presented on the website of the Institute of Applied Astronomy RAS.

Halley - Electronic Catalogue of Comets is a free application to work with the comets database, containing Keplerian orbital elements, non-gravitational and physical parameters of the comet, and other data. The database is updated in case the new data become available. The tasks performed by the electronic catalogue include calculation of the orbital evolution of comets and visualization of comet dynamics, detection of close approaches with the major planets in a given time interval, as well as a number of other tasks.
