Observable Comets

• the latest MPEC list of observable comets
• a list of comets discovered in the past year
• an interactive converter between old- and new-style designations
• dates of last observation for currently-observable comet
• the text of the 1994 IAU resolution implementing the current comet designation system
• orbital elements in forms suitable for loading into popular planetarium-type programs
• recent magnitude estimates of comets as reported to the International Comet Quarterly (links to the magnitudes are also given from the pages for individual comets shown below).

Orbital elements and ephemerides are available for the following unnumbered comets:
