It appears that Mercury has come into view heading in front of the Sun today -

It will be seen moving faster than the stars using the stationary Sun as a central reference insofar as the change in position of the background stars to the central Sun, due solely to the orbital motion of the Earth, contrasts with the faster motion of the Mercury just as the ancient astronomers named that planet for its swift motion.

It gives such an intimate perspective of the solar system as though planetary transits are no longer a rare event but their transition from left to right and in front of the Sun along with the new perspective from right to left and behind the Sun are as seamless and observable as Jupiter's satellites around their parent planet.
