cds-question@unistra.frinterferometrymultiple-starsinfrared-astronomyvisible-astronomyResults of the speckle-interferometry observations at the 4.1m Southern Astrophysical Research Telescope obtained during 2023 are presented: 1913 measurements of 1533 resolved pairs or subsystems (median separation 0.16") and nonresolutions of 552 targets; 42 pairs are resolved here for the first time. This work continues our long-term effort to monitor orbital motion in close binaries and hierarchical systems. A large number (147) of orbits have been determined for the first time or updated using these measurements. Complementarity of this program with the Gaia mission is highlighted.2024AJ....168...28Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/168/28CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/wds : The Washington Visual Double Star Catalog (Mason+ 2001-2020)I/350 : Gaia EDR3 (Gaia Collaboration, 2020)I/357 : Gaia DR3 Part 3.
