The story
On the night of 25 April 2032 a total lunar eclipse unfolds over Asia and Oceania. From Seoul the whole event falls in the evening hours — a comfortable eclipse to watch on the way home from work. The Moon rises in the east and then passes through penumbral, partial and total phases in turn.
Unlike a solar eclipse, a lunar eclipse is shared by the entire night hemisphere at the same moment. No equipment is needed and it is safe to the naked eye, and the colour of the totally eclipsed Moon — bright orange to deep brick red — differs each time with the volcanic ash and dust in Earth's atmosphere.
The spring constellations stand beside the eclipsed Moon. The sky darkens briefly during totality and stars normally lost in city light come out around the red Moon — at this eclipse Spica in Virgo is expected to lie nearby.
It is the first lunar eclipse with totality fully visible from Korea since November 2022. The sky view replay moves to Seoul's sky an hour and a half before maximum and tracks the Moon. Precise contact times will be updated as the date approaches.
Why it matters
Korea saw only the partial phases of the March 2026 eclipse, and the eclipse of 31 December 2028 falls in the evening but with short totality. The two total eclipses of April 2032 and October 2033, both fully visible in the evening, are a rare combination — the best lunar-eclipse opportunities for this generation of Korean observers.
A lunar eclipse makes visible the 5° tilt of the Moon's orbit to the ecliptic — the reason there is no eclipse at every full Moon, and why totality comes only when full phase and a node crossing coincide. The curved edge of Earth's shadow was Aristotle's evidence that the Earth is round.
During totality the Moon dims ten-thousand-fold and its surface temperature drops by more than 100 °C. Orbiters measure that sudden cooling to estimate the thermal properties of the lunar soil — the scientific use of a lunar eclipse.
How to watch
Choose the April 2032 eclipse in the sky view's event list to move to Seoul's evening sky and replay the Moon's whole passage through Earth's shadow. Selecting the Moon gives its altitude, bearing, phase and 24-hour track from your location.
The orbit view replay shows the Sun–Earth–Moon alignment together with Earth's shadow cone; how far the Moon passes from the centre of the shadow sets the length of totality.
The same year brings a transit of Mercury on 13 November 2032, followed by the total lunar eclipse of 8 October 2033 — all three reachable from the sky view's event list.

Background
Total lunar eclipses occur zero to three times a year, and one fully visible in the evening from a given region comes only every few years. The April 2032 eclipse falls in the evening for East Asia and Australia and before dawn for western North America.
Contact times are known in advance to the minute from lunar-orbit calculations; this simulator's Moon uses an abridged ELP series after Meeus with about 10 arcseconds of precision. The time given is for maximum eclipse, and the partial-phase times will be updated as the date approaches.
The partner solar eclipse is the partial eclipse of 9 April 2032 (high northern latitudes) two weeks earlier, and the next lunar eclipse of the same Saros series falls on 6 May 2050.
The Danjon scale used to record the Moon’s colour during an eclipse has five steps, from 0 (an almost invisible black Moon) to 4 (bright copper or orange). Eclipses after major volcanic eruptions are dark, 0 to 1, because of stratospheric aerosols, and in clear years bright, 3 to 4; the nearly black eclipse of 1992, the year after Pinatubo, is the well-known example. The rating of the April 2032 eclipse will be set by volcanic activity at the time, and recording it by eye and reporting it is citizen science anyone can join.
FAQ
Is the whole eclipse visible from Korea?
Yes — from Seoul the whole event, penumbral to total, falls in the evening hours.
Is equipment needed?
No. It is safe to the naked eye; binoculars show the colour changes on the surface better.
Why does the Moon turn red?
Only the red wavelengths of sunlight, bent through Earth's atmosphere, reach into the shadow.
When is Korea's next total lunar eclipse after this?
The evening of 8 October 2033, when the Moon rises already in eclipse.
