When to see the Moon and Mercury: June 4, 2019 

Look to the northwest just after sunset tonight, Tuesday, June 4, 2019, and you’ll see a 2% illuminated Crescent Moon appear in the dusk close to the horizon. That in itself will be a grand sight, and for this month only, it’s a sighting that sees the Islamic month of Ramadan officially cease. As well as the delicate crescent of light on the Moon, you should be able to make out Earthshine on the rest of our satellite. That’s sunlight reflected from Earth onto the Moon. It’s always there, but it’s only possible to detect with the human eye when the moon is very young.
