  • AUID is the AAVSO Unique Identifier for the star. When reporting a problem, please include this AUID.
  • Coordinates are in J2000 sexagesimal format, followed by decimal degrees
  • Search for variable stars in this field via VSX
  • Label is that star's label when plotted on an AAVSO chart, usually (but not always) its V magnitude rounded to the nearest tenth.
