In 2016, the IAU organized a Working Group on Star Names (WGSN) [16] to catalog and standardize proper names for stars. The WGSN approved the name Almach for the component Gamma Andromedae A on 20 July 2016 and it is now so included in the List of IAU-approved Star Names. [13] Almach was the traditional name (also spelt as Almaach, Almaack ...

The star is in almost all depictions part of the main asterism of Pegasus and Andromeda. [18] In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN) [19] to catalog and standardize proper names for stars. The WGSN's first bulletin of July 2016 [20] confirmed Alpheratz as the name for the main star.
