摘要：A series of cultural and scientific activities were organized along the Baja California Peninsula both to observe the transit of Venus of June 5, 2012, and to commemorate the transit of June 3, 1769, by measuring the shadow of Venus from the same location.1 The events were coordinated by the Universidad Nacional Autónoma de México (UNA M) and local authorities. Major celebrations took place in the central plaza of San José del Cabo, not far from where the combined French/Spanish expedition observed the transit in 1769, and a search was carried out to find the location of the previous effort. Upon finding clear evidence of the 1769 site, an observatory was built and the transit measured from where Joaquín Velázquez de León held his telescope in June 1769.2
