  The results of speckle interferometric observations at the 4.1 m Southern
Astrophysical Research Telescope (SOAR) in 2019 are given, totaling 2555
measurements of 1972 resolved pairs with separations from 15 mas (median 0.21")
and magnitude difference up to 6 mag, and non-resolutions of 684 targets. We
resolved for the first time 90 new pairs or subsystems in known binaries. This
work continues our long-term speckle program. Its main goal is to monitor
orbital motion of close binaries, including members of high-order hierarchies
and Hipparcos pairs in the solar neighborhood. We give a list of 127 orbits
computed using our latest measurements. Their quality varies from excellent (25
orbits of grades 1 and 2) to provisional (47 orbits of grades 4 and 5).
