Spain and much of Europe witnessed a partial lunar eclipse in the early hours of Friday, as the Earth's shadow covered nearly the entire Moon. The phenomenon began at 4:34 and reached its maximum at 6:12, with the eclipse ending at 7:52 peninsular time. At its peak, about 93% of the lunar surface was hidden, creating a clear visual spectacle visible without any special equipment.
The eclipse unfolded in five distinct phases, starting with a subtle penumbral stage in which the Earth's shadow blurred the Moon's edge. As the event progressed, a pronounced darkening appeared on the upper left of the lunar disk, marking its entry into the umbra. Unlike the total solar eclipse earlier this month, which required certified protective glasses, this lunar event was safe to observe with the naked eye.
Across Spain and Europe, the Moon appeared to slip behind famous landmarks. In Rome, it was nestled among the arches of the Coliseum, while in Slovakia, the lunar disk hovered near the walls of Halic Castle. In Córdoba, the full Moon, known in August as the sturgeon moon, was photographed above the Torre de la Calahorra, adding to the night's memorable images.
Partial lunar eclipses differ from total ones because only a portion of the Moon enters the Earth's darkest shadow, the umbra. This creates the characteristic 'bite' effect, with a large segment of the lunar surface shaded while a thin arc remains illuminated. During the maximum phase, only a faint sliver of light was visible on the upper right, as the rest of the Moon was enveloped in shadow. In the final stages, the Moon gradually regained its brightness as it emerged from the Earth's shadow.
Although the term 'blood moon' is reserved for total eclipses, the depth of this partial eclipse allowed reddish and orange hues to appear on the shadowed portion. The Earth's atmosphere filters sunlight, scattering shorter blue wavelengths and allowing longer red wavelengths to reach the Moon's surface. Such events continue to attract skywatchers and photographers eager to capture rare celestial moments.
The eclipse followed closely after the total solar eclipse of August 12, which drew its own wave of excitement and required special viewing precautions. The contrast between the two events shows the range of astronomical phenomena visible from Spain this summer. The lunar eclipse also coincided with unusually cool August weather in parts of the country, as a polar air mass recently brought Madrid its coldest August day since 1998, information from recent reports.
Lunar eclipses occur when the Earth aligns directly between the Sun and the Moon, casting a shadow visible from anywhere on the planet's night side. The August sturgeon moon, named after the traditional fishing season in North America, added context to the event. For many in Spain and across Europe, the spectacle offered a rare chance to see light and shadow play across a nearly full Moon, framed by some of the continent's most iconic architecture.
