NASA: Mercury Transit 2016
Science at NASA: ScienceCasts: The 2016 Transit of Mercury (updated).
I watched part of the transit (which started at 1:13pm and ended at 8:40pm here in Germany) at school, where we had two telescopes and a sun projector set up so everyone could have a look. Like the solar eclipse last year we were very lucky with the weather, as it was sunny throughout the afternoon.
