* These local times do not refer to a specific location but indicate the beginning, peak, and end of the eclipse on a global scale, each line referring to a different location. Please note that the local times for Washington DC are meant as a guideline in case you want to view the eclipse via a live webcam. They do not mean that the eclipse is necessarily visible there. Times should be accurate to a few seconds.

** The geocentric times refer to a theoretical situation where the transit is viewed from the Earth's center. They are used to provide an approximately average time schedule for astronomical events. Because of varying perspectives, observers on the Earth's surface will experience the transit at slightly different times depending on their location.

Geocentric duration of this Mercury Transit is 5 hours, 27 minutes, 12 seconds.
