However what’s an annular eclipse? How is it completely different from a partial or complete photo voltaic eclipse? And the place are you able to see the ring of fireside?
When is the annular photo voltaic eclipse?
The subsequent photo voltaic eclipse will happen on 14 October 2023. It’s an annular eclipse, with many dubbing it the ‘Nice American Eclipse’ because of the spectacular ring of fireside that can journey throughout eight US states, Mexico and South America.

The place will the annular eclipse be seen?
The annular photo voltaic eclipse will probably be seen from North, Central, and South America on 14 October 2023.
All of America and Canada will expertise a partial photo voltaic eclipse on this date, however only some US states together with Mexico and South America will see the spectacular ‘ring of fireside’. These fortunate sufficient to be within the path of the annular eclipse will even expertise a partial eclipse earlier than and after the ring of fireside.
The ring of fireside will journey throughout eight states, then cross into South America passing over Northern Brazil earlier than ending within the Atlantic Ocean at sundown – a spectacular sight for any ships within the neighborhood to see an annular photo voltaic eclipse sinking under the horizon.
The primary US state to see the ring of fireside will probably be Oregon, adopted by California, then Nevada, Utah, Arizona, Colorado, New Mexico, and Texas.
The trail of the annular photo voltaic eclipse will then transfer throughout Mexico, then Belize, Honduras, Nicaragua and Costa Rica.
After that, it is going to move over Panama, then Colombia and Brazil, earlier than ending within the Atlantic Ocean.
From begin to end, the eclipse on 14 October will final for round 2.5 hours in complete:
- Partial photo voltaic eclipse: Roughly 1 hour, quarter-hour
- Annular photo voltaic eclipse: Roughly 4-5 minutes
- Partial photo voltaic eclipse: Roughly 1 hour, quarter-hour
Sorry UK viewers, this photo voltaic eclipse is just not seen from our facet of the pond.
What does an annular eclipse appear to be?
An annular eclipse, aka ring of fireside, appears to be like precisely what it feels like; a fiery, radiant halo in opposition to a darkened sky. It occurs when the Moon is immediately in entrance of the Solar, leaving solely the outer fringe of the Solar seen across the fringe of the Moon.
Not each photo voltaic eclipse will end in a hoop of fireside, nevertheless, the Moon should be far sufficient away from us in its elliptical orbit to not block out the entire Solar.
What’s an annular photo voltaic eclipse?
An annular eclipse (aka ring of fireside eclipse) is a sort of photo voltaic eclipse that happens when the Moon passes immediately in entrance of the Solar, however doesn’t fully block out the sunshine. Because of this, the Solar’s periphery, often known as the ‘ring of fireside’ or the ‘annulus’, stays seen across the Moon, like a halo of sunshine.
As a result of the Moon orbits the Earth in an ellipse, the space between the Earth and the Moon varies all year long. For an annular eclipse to happen, the Moon should be in its new Moon section, and much sufficient away from Earth in order that it appears to be like small. It’s due to this fact unable to fully block out the Solar’s central disc.
Annular eclipses are visually putting and happen much less often than partial (when solely a portion of the Solar is obscured by the Moon, leading to a crescent-shaped Solar) and complete photo voltaic eclipses (when the Moon fully covers the Solar). Annular eclipses are a uncommon deal with, and one that you simply’ll bear in mind for a few years to return.
When is the following photo voltaic eclipse?
For the UK, the following photo voltaic eclipse will probably be a partial eclipse in March 2025, however we’ve bought a very long time to attend till the following complete eclipse; September 2090.
Here’s a record of upcoming photo voltaic eclipses worldwide:
- 14 October 2023: Annular photo voltaic eclipse, North & South America
- 8 April 2024: Complete photo voltaic eclipse, Mexico, US & Canada
- 2 October 2024: Annular photo voltaic eclipse, Easter Island & Chile
- 29 March 2025: Partial photo voltaic eclipse, UK & Europe
- 21 September 2025: Partial photo voltaic eclipse, New Zealand
- 17 February 2026: Annular photo voltaic eclipse, Southern Chile
- 12 August 2026: Complete photo voltaic eclipse, Iceland and Spain
Why does a photo voltaic eclipse solely occur throughout a brand new Moon?
A photo voltaic eclipse can solely occur throughout a brand new Moon section. It’s because throughout a brand new Moon, the Moon is situated between the Solar and the Earth – which is the place the Moon must be with the intention to block out gentle from the Solar. It’s fairly easy when you concentrate on it!
Whereas on this straight-line configuration, the Moon is ready to move in entrance of the Solar (from our viewpoint on Earth), and we get a photo voltaic eclipse.
Nevertheless, not each new Moon will end in a photo voltaic eclipse, so we don’t get them each month. It’s because the Moon orbits the Earth on a aircraft that’s barely completely different from Earth’s orbit across the Solar, by round 5 levels. This small distinction is often sufficient so the brand new Moon can move above or under the Solar, with out blocking out the Solar – so no eclipse.
Which means photo voltaic eclipses can solely happen when the Moon passes by Earth’s orbital aircraft, throughout a brand new Moon section.
Why don’t photo voltaic eclipses final so long as lunar eclipses?
Throughout an eclipse, totality can vary from just some seconds to minutes, whereas for a lunar eclipse, totality can final for an hour – with the entire occasion lasting a number of hours.
This distinction is right down to the completely different relative sizes of the Earth and Moon, i.e., the physique casting the shadow. In a lunar eclipse, it’s the Earth casting a shadow onto the Moon, whereas in a photo voltaic eclipse it’s the Moon casting a shadow onto the Earth.
Tips on how to view the annular photo voltaic eclipse on 14 October:
For these of us not within the path of the eclipse, you’ll be able to nonetheless watch it by way of the official NASA broadcast on their YouTube channel, which begins streaming at 4:30pm on 14 October 2023.
Should you’re fortunate sufficient to be able to look at the eclipse, both partial or annular, make sure you put on eye safety. There are particular purpose-made eclipse glasses, or handheld photo voltaic viewers that you would be able to purchase. These are completely different from common sun shades; they’re a lot darker and adjust to the ISO 12312-2 worldwide customary for filters for direct viewing of the Solar.
By no means look immediately on the Solar.
And please don’t take a look at the Solar by a digicam, telescope, binoculars, or every other optical gadget, because it is not going to solely burn by the filter – but in addition injure your eyes.
One other technique to view the eclipse is by utilizing a pinhole projector. It’s an oblique methodology, and also you’ll want one thing with a small gap in it, like a gap punched into a bit of card or a colander (the latter is enjoyable since you’ll find yourself with a lot of Suns). Stand with the Solar behind you, and maintain your DIY projector above a easy white floor, like a bit of white copy paper positioned on the bottom, and a picture of the Solar will probably be projected onto the paper under. It’s a enjoyable venture, and a good way to view the eclipse safely!
