You could witness the rare sight of Comet Neowise this evening - though you will have to set an alarm.
Clear skies have meant that many people have already seen the newly discovered comet, but the perfect time to spot it is coming up.
Comet Neowise reached its closest point to the sun on July 3 and is expected to reach its closest point to Earth in just a couple of days time.
This means it could be easier to see the comet late tonight or in the early hours of tomorrow morning.
The comet was discovered in late March by a space telescope and will be visible over the UK throughout July.
The comet is rare because it survived a close encounter with the sun, passing it at around the same distance as Mercury, the planet closest to the sun in our solar system.
Mercury travels around the sun in only 88 days and is the smallest planet, only a little larger than the moon.
To spot Comet Neowise, you will need to get up really early or stay up very late.
In mid-July, the comet is most visible around 80 minutes before the sun rises, so your best chance at spotting it is shortly after 3.30am.
How to see it
The comet is visible to the naked eye, and without a telescope, because it's so bright.
You don't need binoculars to see it, but if you have a pair, they will intensify the view.
It will look like a blurry star with a bit of a tail.
The best way to catch a glimpse is to look out for the most famous constellation in the Northern Hemisphere's sky, the Big Dipper, also known as the Plough.
If you look eastwards on a clear night in an area with low light pollution, you should be able to spot it.
Neowise will be below the Big Dipper and around 10 degrees above the horizon.

"So, on these mornings, the head of Comet Neowise will appear about ‘one fist’ up from the north-east horizon."
The comet passes closest to Earth on July 23, when it will be below and just to the right of the Big Dipper.
On July 25, it will be directly under it - before continuing to move west and slightly upwards.
The comet won't return to our skies for another 6,800 years so it's a sight well worth seeing.
