BBC.com are signposting a rare transit of Mercury between our Father The Sun and Earth:
“Mercury’s sojourn between Earth and our star lasted from 11:12 until 18:42 GMT.
“It was the third such pass of 14 this century; the little planet will not transit again until 2019 and then 2032.
“The event is impossible – and dangerous – to view with the naked eye or binoculars, but astronomy groups worldwide offered the chance view it through filtered telescopes.
“Views of the spectacle from space and ground telescopes were also streamed online.
“They showed Mercury as a tiny black circle, smaller but darker than many sunspots, slowly traversing the Sun’s giant yellow disc.”
No info on how this might impact the supposed effects of Mercury being in retrograde – along with 4 other planets!
