|April 20th, 2023 Hybrid Solar Eclipse. Partial from Canberra, total from Exmouth W.A.
A hybrid eclipse is one where the eclipse is annular in one part of the central path and total in others. Next year's eclipse is a total eclipse as seen from the Cape Arid National Park around Exmouth, WA. Cape Arid is the only region in Australia where a total eclipse can be seen. It can also be seen as total from parts of Timor-Leste and Eastern Indonesia. The rest of the Australian continent will observe a partial solar eclipse. Accommodation on the peninsula is very tight and has been difficult to secure for the past two years. It gets booked up as soon as it is released. Soft-top accommodation starts at around $550 for a minimum 6 night stay and hard-top packages range from $3000 to over $10000. I have been to 14 total eclipses in far flung corners of the world and in my experience this has been one of the most difficult eclipses I've experienced to secure accommodation. Australia will experience another 4 total eclipses over the next 15 years in 2028, 2030, 2037, 2038. All these eclipses are visible as total from the eastern states over wide areas. One passes over Sydney, Another over the southern part of greater Brisbane. If you can wait for the later eclipses, then wait. If you want to try to find accommodation for next years eclipse, contact me and I'll point you in the direction of some resources to help.
From the ACT region, a partial eclipse will be observed on April 20. The eclipse will have a magnitude of 0.19 and an obscuration of 9.5%.
Magnitude: the ratio of the overlap of the diameters of the Sun and Moon. About one fifth of the Sun's diameter will be covered.
Obscuration: is a measure of the Sun's area covered by the Moon expressed as a percentage. 9.5% of the Sun's surface area will be covered.
