Important note: the two panoramic ITEK-camera frames mentioned in the LPI's list of orbital Aristarchus A photographs show only the eastern shadowed inner slopes of it (AS15-P-10326) and nothing but the cobrahead-shaped "source" of Rima Aristarchus IV immediately east of it (AS15-P-10331).
The whole of Aristarchus A (Vaisala) was captured on the two frames following the above mentioned: AS15-P-10328 and AS15-P-10333.

Additional Information


Nomenclature

  • Named for Yrjo Väisälä (9/6/1891 – 7/21/1971), a Finnish astronomer and physicist. His main contributions were in the field of optics, but he was also very active in geodetics, astronomy and optical metrology.
  • This replacement name for a formerly lettered crater was introduced on LTO-39A4 (for which it served as the chart title). It appears in the cumulative list of approved names in IAU Transactions XVB (1973). Since it does not appear in any prior IAU Transactions, it was probably approved at the 1973 meeting. Biographical information was unofficially reported in Ashbrook, 1974. - Jim Mosher
  • In their book The Moon, Percy Wilkins and Patrick Moore called a certain crater near Catena Sylvester "Vaisala".
