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 2.1 days before [[Apsis|apogee]] (on March 8, 1905, at 7:00 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=1905&n=136|publisher=timeanddate|access-date=30 July 2024}}</ref>

Annularity was visible from [[Heard Island and McDonald Islands]] (now an [[States and territories of Australia|Australian external territory]]), [[Australia]], [[New Caledonia]], and [[New Hebrides]] (now [[Vanuatu]]). A partial eclipse was visible for parts of [[Madagascar]], [[Antarctica]], [[Australia]], and [[Oceania]].

== 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]].
