An annular [[solar eclipse]] occurred at the Moon’s [[Lunar node|descending node]] of orbit on Wednesday, October 2, 2024,<ref>{{cite web|title=October 2, 2024 Annular Solar Eclipse|url=https://www.timeanddate.com/eclipse/solar/2024-october-2|publisher=timeanddate|access-date=13 August 2024}}</ref> with a [[Magnitude of eclipse|magnitude]] of 0.9326. A [[solar eclipse]] occurs when the [[Moon]] passes between [[Earth]] and the [[Sun]], thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's [[apparent diameter]] is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an [[Annulus (mathematics)|annulus]] (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. Occurring about 2 hours before [[Apsis|apogee]] (on October 2, 2024, at 20:40 UTC), the Moon's apparent diameter was smaller.<ref>{{cite web|title=Moon Distances for London, United Kingdom, England|url=https://www.timeanddate.com/astronomy/moon/distance.html?year=2024&n=136|publisher=timeanddate|access-date=13 August 2024}}</ref>

Other than [[Easter Island]] and a small portion near the southern tips of [[Argentina]] and [[Chile]] and the north of the [[Falkland Islands]],<ref>{{Cite web |date=2024-10-01 |title=An annular solar eclipse on October 2, 2024 |url=https://earthsky.org/astronomy-essentials/an-annular-solar-eclipse-on-october-2-2024/ |access-date=2024-04-09 |website=earthsky.org |language=en-US}}</ref> the path of the eclipse's [[umbra, penumbra and antumbra|antumbra]] occurred over the [[Pacific Ocean]]. The penumbra was visible from [[Hawaii]], eastern [[Oceania]], southern and central [[South America]], the southwesternmost parts of [[Mexico]] (more specifically, [[Baja California del Sur]] and [[Jalisco]]), and portions of [[Antarctica]]. Approximately 175,000 people live in the path of annularity.<ref>{{Cite web |title=What the Eclipse Will Look Like near the Maximum Point |url=https://www.timeanddate.com/eclipse/solar/2024-october-2 |access-date=2024-05-12 |website=Time and Date}}</ref><ref>{{Cite web |last=Carter |first=Jamie |date=2024-04-09 |title=Annular solar eclipse 2024: Everything you need to know about the next solar eclipse |url=https://www.space.com/annular-solar-eclipse-oct-2-2024-guide |access-date=2024-05-12 |website=Space.com}}</ref>

== Eclipse season ==
{{See also|Eclipse cycle}}
This eclipse is part of an [[eclipse season]], a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) later; thus two full eclipse seasons always occur each year. Either two or three eclipses happen each eclipse season. In the sequence below, each eclipse is separated by a [[fortnight]].
