Mercury at greatest elongation east

Thursday, 2018, July 12 - 05:00

Across much of the world Mercury will be well placed for observation in the evening sky, shining at mag 0.6.

From the UK, however, it will not be observable – it will reach its highest point in the sky during daytime and will be no higher than 5° above the horizon at dusk.

Mercury in coming weeks

Over coming weeks, the distance between Mercury and the Sun will decrease each night, and it will gradually sink back into the Sun's glare, as the table below indicates (all times given in London local time).
