A transit of Venus occurred on 9 December 1874.
Notes on verification
Multiple authoritative sources including HM Nautical Almanac Office (official astronomical records), museum archives, academic research papers, and well-documented Wikipedia articles all independently confirm the December 9, 1874 date with specific UTC timing (01:49 to 06:26). The minor date variation (Dec 8-9) is explained by time zones and represents expected documentation patterns for global astronomical events.
