Signalling the start of summer in the Northern Hemisphere and the start of winter below the equator, the summer solstice is here.
It will take place on Wednesday 21 June at 15:57 BST.
It marks the longest day and shortest night of the year, and 2023 is expected to bear witness to a solstice gathering of the moon, Mars and Venus.
According to Stellarium charts, these will be visible in London as they head towards the western horizon.
What is the summer solstice?
During a summer solstice, there is more daylight during the day and the hours during the night are at a minimum.
“Most people consider the summer solstice to be a day, it is in reality an exact moment in time that falls upon that day. This moment comes when whichever hemisphere you’re in is most tilted towards the Sun,” the Royal Museums Greenwich has said.
How to watch
Although it may be possible to view with the naked eye – binoculars or a telescope will hopefully provide a more visible close-up view of the three planets.
Venus can be viewed in the daytime and will look like a bright speck of white light against the blue sky.
Once the sun sets, the moon, Venus and Mars are expected to become more visible.
According to Space.com – Mars will be close to Venus – it adds: “About 4 degrees to its upper left, appearing to shine rather feebly, will be Mars. You’ll likely need binoculars to see it at all in the bright twilight even after Venus becomes obvious.”
