A total lunar eclipse, known as a "Blood Moon," will be visible across South Korea on Monday, coinciding with Jeongwol Daeboreum, the first full moon of the lunar new year. This marks the first time a total lunar eclipse has occurred on this traditional holiday since 1990.
According to the Korea Astronomy and Space Science Institute, the entire eclipse will be observable from all regions of South Korea if weather conditions permit. A total lunar eclipse occurs when Earth positions itself directly between the sun and moon, casting its shadow over the lunar surface. However, the Korea Meteorological Administration forecasts cloudy conditions across many regions Monday evening, potentially requiring extended viewing periods for successful observation.
The eclipse sequence begins with a penumbral phase as the moon enters Earth's partial shadow, followed by a partial eclipse starting at 6:49:48 p.m. The total eclipse phase commences at 8:04 p.m., reaching maximum coverage at 8:33:42 p.m. At peak totality, the moon will be positioned approximately 24 degrees above the eastern horizon. The total eclipse concludes at 9:03:24 p.m., with the partial phase ending at 10:17:36 p.m.
During the approximately one-hour total eclipse, observers will see a darker, reddish moon. This distinctive coloration occurs as sunlight passing through Earth's atmosphere refracts toward the moon, with blue light scattering while red wavelengths reach the lunar surface.
For optimal viewing, the institute recommends locations with unobstructed sightlines. The eclipse is visible to the naked eye, and smartphone night photography modes can capture the phenomenon. The event will be observable across East Asia, Australia, the Pacific region, and the Americas. The next total lunar eclipse visible from South Korea is scheduled for December 31, 2028.
Public observation programs will be held at venues nationwide, including Bohyunsan Astronomical Science Museum, Gwacheon National Science Museum, and Starlight Nuri Park in Jeju City.
