Additional Information


  • Sinus Aestuum was part of the original IAU nomenclature of Blagg and Müller (1935).
  • Section of the Face of the Woman in the Moon.
  • Section of Ed Murray's C or Dark C.
  • The name Sinus Aestuum is Latin, according to the IAU, for "Seething Bay", or according to Whitaker, "Bay of Seething Heat" (p. 87) or "Bay of Hot Days" (p. 216).
    • In a review of their book in the February 1955 JBAA (page 121), Whitaker criticizes Wilkins and Moore for translating the name as "Bay of Heat," saying the correct translation is "Bay of Billows."
  • According to Whitaker (pp. 216-217), this name was introduced by Riccioli, although Riccioli used it for the feature now known as Sinus Medii. Blagg, in her Collated List (#1270), found the present feature labeled with its modern name by all the authorities she consulted. Whitaker does not specify who moved it to its present location.
  • Van Langren had previously referred to this area (plus Mare Vaporum) as Fretum Catholicum (Whitaker, pp. 192 and 200).
  • Aestuum Pyroclastics, an unofficial name on chart 17 of the 21st Century Atlas of the Moon (C.A. Wood/ M. Collins). The location of the Aestuum Pyroclastics is north-northwest of Schroter, at the same location of F.v.P. Gruithuisen's so called "lunar city".
