THE EXPERIENCE
What it was actually like
A distinct bite was taken out of the Sun, reaching 53.7% at maximum. Daylight barely changed — the eye adapts far too well for that — so this was an eclipse you had to know about in advance to notice. Anyone watching needed a filter; the remaining Sun was as dangerous as an uneclipsed one.
04 · POSITION
Where was it seen?
This eclipse was partial everywhere on Earth — the Moon's dark shadow passed above or below the planet entirely, so there was no path of totality to travel to, from Amundsen-Scott or anywhere else.
