The SuperCOSMOS Sky Survey (or SuperCOSMOS Sky Surveys or SSS) is a survey producing catalogs by scanning legacy photographic plates from earlier survey efforts, using an automated plate measuring/scanning device named SuperCOSMOS, a scanning project carried out by the Royal University of Edinburgh (ROE). SuperCOSMOS was a follow-on to earlier plate measuring/scanning devices and associated projects, the first called GALAXY (for General Automatic Luminosity And X-Y), and the second called COSMOS (for Coordinates, Sizes, Magnitudes, Orientation, and Shapes). Among the plates scanned are some from POSS, POSS-II, the UK Schmidt Survey, and ESO Schmidt Telescope surveys. The effort has revealed unnoticed nearby and high-proper motion stars captured by the plates, given designators, SCR, and SSSPM.
SuperCOSMOS-RECONS (SCR) specifically aims at proper motions of nearby stars.
The SuperCOSMOS Hα Survey (SHS) is from the plates of the AAO/UKST-hα Survey, a photographic survey using a narrowband filter aimed at detecting H-alpha.
