An earthquake
catalog or catalogue is a list or tabulation of
earthquakes within a particular region. In most earthquake catalogs, each earthquake is listed by date and time of occurrence, typically in UTC (
Coordinated Universal Time) format. The format of a catalog entry is as follows: "year-month-day hour:minute:second UTC" (e.g. 2015-04-17 09:08:06 UTC). Additional information may include the estimated
magnitude, and location of the earthquake.
MessierCatalog - The Messier objects are a set of astronomical objects first listed by French astronomer Charles Messier in 1771. Nebulae and Star Clusters was published in 1781, with objects
M1 – M110.
New General Catalogue compiled in the 1880s by J. L. E. Dreyer, lists objects
NGC 0001 – NGC 7840. The NGC is one of the largest comprehensive catalogues, as it includes all types of deep space objects and is not confined to, for example, galaxies.
Henry DraperCatalogue published between 1918 and 1924, lists more than 225,000 of the brightest stars, named using HD followed by a 6-digit number.
Sir
Patrick Moore compiled the
Caldwell catalogue in 1995 to complement the Messier catalog, listing 109 bright star clusters, nebulae, and galaxies named C1 to C109. (This is a list of favorite[citation needed] deep-sky objects and not a catalog in the astronomical sense. Other deep-sky observing lists for amateur astronomers predated it.)
2MASS is the most ambitious project to map the night sky to date. Goals included first detection of brown dwarfs, an extensive survey of low mass stars, and cataloguing of all detected stars and galaxies. More than 300 million point sources and 1 million extended sources were catalogued....
