The results of speckle interferometric measurements of binary and multiple stars conducted in 2008 and2009 at the Blanco and SOAR 4 m telescopes in Chile are presented. A total of 1898 measurements of1189 resolved pairs or sub-systems and 394 observations of 285 un-resolved targets are listed. We resolvedfor the first time 48 new pairs, 21 of which are new sub-systems in close visual multiple stars. Typicalinternal measurement precision is 0.3 mas in both coordinates, typical companion detection capability is-4.2 at 0'.'15 separation. These data were obtained with a new electron-multiplication CCD camera; dataprocessing is described in detail, including estimation of magnitude difference, observational errors, detectionlimits, and analysis of artifacts. We comment on some newly discovered pairs and objects of special interest.
