Beginning in the Indian Ocean at sunrise and ending at sunset in the Pacific, most of the path of this hybrid total solar eclipse \u2013 which has become known as the Ningaloo Eclipse \u2013 is at sea, visiting only brief strips of land in Western Australia, Timor-Leste and West Papua.<\/p>\n

That\u2019s not to be, though it\u2019s estimated that at least 20,000 people<\/a> will travel to experience no more than 76 seconds of totality.<\/p>\n

However, this is set to be a very rare kind of solar eclipse that occurs only seven times in the 21st century.<\/p>\n
For this eclipse, the match-up between the apparent size of the Moon and Sun is so similar during totality that eclipse-chasers will likely see an extended display of Baily\u2019s beads<\/a> as a broken ring around the Moon just before and after totality (some of you may remember the spectacular image that won the 2016 Astronomy Photographer of the Year competition<\/a>).<\/p>\n
That alone is enough to get some eclipse-chasers excited, but should also be possible to observe an unbroken ring of the Sun\u2019s red chromosphere<\/a> just as totality begins and ends.<\/p>\n

There are two types of central solar eclipse: total and annular.<\/p>\n
During a total solar eclipse, the Moon entirely blocks the Sun for a few minutes and allows observers to see the solar corona with their naked eyes.<\/p>\n
During an annular solar eclipse the Moon is slightly too far away from earth in its elliptical orbit, and so doesn\u2019t quite block all of the Moon, resulting in a ring around the Moon that can only be safely observed using solar eclipse safety glasses.<\/p>\n
What happens during a hybrid eclipse is a bit of both.<\/p>\n

If you are close to the sunrise point, then the Moon will appear slightly smaller in the sky compared to if you watch the eclipse from the middle of the path, where you will be slightly closer to the Moon, simply because Earth is a sphere.<\/p>\n
The range is so narrow that hybrid solar eclipses will only occur four more times this century, in 2031, 2049, 2050 and 2067.<\/p>\n
On April 20, 2023, the celestial mechanics are so precise that for a few seconds an annular solar eclipse will occur near to the start and end of the path.<\/p>\n
Practically speaking, this won\u2019t make much difference at all to eclipse chasers because the points where annularity will occur in extremely remote areas of the Indian and Pacific oceans.<\/p>\n

The most popular place will be Exmouth Peninsula (60 seconds from 11:29 am local time), a remote part of Western Australia that the path of totality briefly passes over.<\/p>\n
It\u2019s about 1,270 km north of Perth and 1,400 km south of Broome, but it\u2019s here that has the best weather prospects.<\/p>\n
Around 20,000 people are expected to descend on the tiny town, population of 3,000, mostly in makeshift campsites now being set up<\/a> by the local authorities (organised tours sold out long ago).<\/p>\n

There will also be a few private yachts sailing around the Muiron and Sunday islands (49 seconds from 11:30 am local time), Lowendal Islands (63 seconds from 11:34 am local time) and the remote Ashmore Reef (63 seconds from 4:04 Universal Time).<\/p>\n
The even more intrepid will travel to Timor-Leste, a country of 1.3 million between Indonesia and Australia and ringed by coral reefs teeming with marine life.<\/p>\n

Finally comes West Papua, an even more remote island of 1.1 million where intrepid cruises<\/a> will search for whales and birds of paradise with totality near Gorong Island (71 seconds from 1:40 pm local time).<\/p>\n
An equally remote snorkelling trip<\/a> will experience totality in the Banda Sea near FakFak (70 seconds from 1:44 pm local time).<\/p>\n
How to observe the hybrid eclipse safely and how to watch online<\/strong><\/h2>\n
Although the pre-totality phase is perfectly safe to watch with the naked eye \u2013 that\u2019s why total solar eclipses are so popular \u2013 totality is always book-ended by a partial solar eclipse on either side, which must be viewed only through solar filters or eclipse glasses<\/a>.<\/p>\n
If you\u2019re not going to be in the path of totality this time around then you can watch online.<\/p>\n
Timeanddate.com have confirmed they will be hosting a livestream of the 20 April 2023 hybrid solar eclipse on YouTube, which you can see below.<\/p>\n
