Mercury Transit 2019: The Astronomical History of This Rare Celestial Event

I enjoyed this report and history in astronomy of observing Venus and Mercury transits. The graph showing time from ingress and egress is from left to right. Viewing in a refractor model telescope, the image will be upright but mirror reversed. Right to left :) Tomorrow for me looks party sunny, forecast was better a day or so ago but perhaps I may see some of the celestial event using my refractor telescope.
