On December 8, 1874, British scientists conducted an astronomical expedition to observe the transit of Venus from three separate sites in the Hawaiian Islands.
Notes on verification
Multiple authoritative sources including Royal Observatory Greenwich, Cambridge Digital Library, and archival materials confirm all key details: British expedition, three Hawaiian observation sites (Honolulu, Waimea, Kailua-Kona), December 1874 date, and organizational details. Minor date discrepancy (Dec 8 vs 9) is explained by timezone/local dating conventions. Strong institutional corroboration.
