On the morning of Friday, 20 March, three rare celestial events - a Super New Moon, Spring Equinox, and Solar Eclipse - will all take place.
That means people in the British Isles can see a Supermoon Eclipse.
As a general rule, the further north you are, the more of the Eclipse you'll be able to see.
But islanders can still expect partial vision as the moon's orbit travels in front of the sun.
The map below shows how much of the Eclipse we're likely to be able to see. It also tells us when you'll need to look - at 09:25am from St Helier:
We might have less vision than much of the British Isles, but coverage across Europe ranges from 30% to 98% - so the Channel Islands are still better than many parts of the Continent.
A trinity of unique celestial events:
A Supermoon is when the earth and moon are as close together as they can be. It'll happen the evening before the Eclipse.
It's also the time of the year when daytime and nighttime are of equal duration, hence the 'Spring Equinox'.
This is the last time a Total Solar Eclipse will be visible in Europe, until 2026.
