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).
