Depth data from Kurt Fisher database
  • Westfall, 2000: 1.53 km
  • Viscardy, 1985: 3.7 km


  • Sir Joseph Norman Lockyer (May 17, 1836 – August 16, 1920) was an English scientist, astrophysicist and astronomer. Along with the French scientist Pierre Janssen he is credited with discovering the gas helium. A keen amateur astronomer with a particular interest in the sun, Lockyer eventually became director of the solar physics observatory in Kensington London. To facilitate the transmission of ideas between scientific disciplines, Lockyer established the general science journal Nature in 1869.
  • Crater Lockyer H was called Hill by Hugh Percy Wilkins and Patrick Moore, but the I.A.U. did not accept that name.
  • Hill was a contemporary English selenographer.
  • A curiosity: who was William J. S. Lockyer? See Lightning, Auroras, Nocturnal Lights, and related luminous phenomena (William R. Corliss, The Sourcebook Project, 1982), at GLL2-R6, GLL2-R8, and GLL14-R3. - DannyCaes Apr 15, 2015
