1470: If they are watching our solar transit. Bob Zimmerman BehindtheBlack.com - a podcast by John Batchelor

Photo: In astronomy, a solar transit is a movement of any object passing between the Sun and the Earth. This mainly includes the planets Mercury and Venus.  Here: On May 9, 2016, Mercury passed directly between the Sun and Earth, making a transit of the Sun. Mercury transits happen about 13 times each century. NASA SDO studies the Sun 24/7 and captured the eight-hour event.
