Welcome to the OGLE-III On-line Catalog of Variable Stars

The main goal of this catalog is to record all variable sources located in the OGLE-III fields in the Magellanic Clouds and Galactic bulge. The data currently available include:

The catalog data include basic parameters of the stars (coordinates, periods, mean magnitudes, amplitudes, parameters of the Fourier light curve decompositions), VI multi-epoch photometry collected since 2001, and for some stars supplemented with the OGLE-II photometry obtained between 1997 and 2000, finding charts and cross-identifications with previously published catalogs.

Use the links in the left side of this page (under Database Queries) to go to the query page for a chosen type of variable stars. You will be sent to a separate form where you will be able to browse the data using any set of criteria. The data can be downloaded separately for individual stars or for the whole result of the query.

Please read the News/Changes page often!

Any comments or error reports should be sent to the this email.
