Mercury will briefly reveal itself at dawn tomorrow (June 16) when the planet reaches its furthest 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 near the equator and further south will have the best viewing opportunities.
