Correspondences Of Old- And New-Style Comet Designations

Due to circumstances beyond our control, this script is off-line until further notice. The following form allow one to find the new-style comet designation for the specified old-style designation, or vice versa, or to find the name of a specific comet. Details on the new-style comet designation system are available.

Examples of valid search strings are given below.

Examples Of Valid Designations

A wide range of comet designations may be entered (see examples below, noting the case and formatting of the input).
Searching For New-Style Designations:

Periodic comet numbers          1P          20D         114P
Designations                    C/1994 N1   P/1987 Q3   1995 A1
Mixture                         1P/1066 G1  1P/Halley

Searching For Old-Style Designations:

Roman numerals                  1986 XIV    1881 III
Letter designations             1909c       1987a1
If only a year is entered, the output will generally be all the Roman numeral designations (1994 and earlier) and new-style designations (1995 and subsequent) of the year specified.
Searching For Names:

Complete names                  Mueller 1   Levy-Rudenko
Partial names                   Shoemaker   Mueller
(The first partial name would pick up all the Shoemaker, Shoemaker-Holt, Shoemaker-Levy, etc., comets, while the second would pick up all Mueller's long period and periodic comets.)

If you are uncertain as to whether a new-style designation begins with `P/', `C/' or `D/', it is preferable to omit this prefix. However, entering a P/ designation for a D/ comet will work.

When searching for names, only complete words will be matched. Thus to find all the comets named `Mueller', one must type `Mueller' in full-- `Muel' will not match any comets. As the search is case-sensitive, entering `MUELLER' or `mueller' will also fail to match any comets.
