“I was in an ideal location at an observatory in Hampshire, England, where in the pale light of the pre-dawn, I gathered with a few other enthusiasts to watch the event. | A transit of Mercury is a rare thing. These days it is of no great scientific importance, but it is fascinating to watch nonetheless as an example of the “clockwork” of the Solar System.” David Whitestone
