Skywatchers across the UK could get to see a stunning partial lunar eclipse in the early hours of Friday, but cloud may spoil the spectacle for some.
The Sun, Earth and Moon will line up in the night sky causing the full Moon - nicknamed the Sturgeon Moon - to glow an eerie red.
It will occur shortly before moonset meaning it will be low on the horizon, with the Moon appearing bigger and more dramatic than usual thanks to a phenomenon known as the Moon illusion.
However cloud and rain may obscure the view for some, with the best viewing chances likely to be in the south and east of England, and possibly parts of Northern Ireland and western Scotland.
The eclipse will take place in the early hours of Friday and comes just weeks after the UK experienced its most dramatic partial solar eclipse in nearly 30 years.
It will start at around 02:23 BST as the Moon moves into what is called the penumbra, the faint outer part of the Earth's shadow.
The moon will appear to dim slightly - although this will be barely noticeable to most viewers.
The main partial phase of the eclipse will begin at 03:33 as the Moon starts to enter the darkest part of the Earth's shadow - called the umbra.
It will reach its maximum at 05:12, when around 93% of the Moon will be within the darkest shadow.
The partial eclipse ends at 06:51 but this will not be visible in the UK because the moon will have set below the horizon by then.
Exact moonset times vary across the UK - for instance, 06:00 in Lerwick, 06:15 in London and 06:42 in Enniskillen.

Because the Moon will be very low in the south-western sky, the eclipse could be made more dramatic thanks to something called the Moon illusion.
This is a term for when the Moon appears much larger than it normally would, purely due to its position in the sky - close to the horizon, seen alongside familiar objects on the ground.
It is caused by the way in which our brains process visual information.
A lunar eclipse happens when the Earth passes between the Sun and the Moon, causing the Moon to temporarily move into the Earth's shadow.
