Mercury will briefly reveal itself at pre-dawn tomorrow (June 16) when the planet reaches its farthest separation from the sun as seen from Earth, also known as its greatest western elongation.

The elusive planet Mercury will reach a maximum angle of 23° west of the sun; viewers located near the Equator and farther south will experience the best viewing opportunities.
