Lunar Eclipse 93% Coverage: Timing and Viewing in Argentina

The deep partial lunar eclipse on August 27-28, 2026 will cover 93 % of the Moon’s diameter. It can be seen with the naked eye from anywhere in the country, with key times: start at 22:24, maximum at 01:13, and end at 04:02. The Galileo Galilei Planetarium offers a free evening with telescopes.

Dates and Coverage

The deep partial lunar eclipse will occur between the night of Thursday 27 and the early morning of Friday 28 August 2026. Earth’s shadow will cover approximately 93 % of the Moon’s diameter at its peak, though the Moon will not be completely obscured.

Timing in Argentina

According to the official schedule, the penumbral phase begins at 22:24 on Thursday 27. At 23:34 the partial eclipse starts, when the shadow moves across the lunar surface. The point of maximum coverage is reached at 01:13 on Friday 28, when 93 % of the lunar disk is in shadow. The partial phase ends at 02:52 and the eclipse is fully over around 04:02.

Viewing Without Protection

A lunar eclipse poses no risk to the eyes, unlike solar eclipses. Adrián González, science communicator at the Galileo Galilei Planetarium, explains that it can be watched with the naked eye, provided the sky is clear. No telescope or binoculars are required; however, these instruments can help appreciate the Moon’s surface details.

Location and Conditions

To enjoy the event, it is recommended to choose a site with low light pollution, away from the bright lights of major cities. Observation will be possible across all of Argentina if weather conditions allow.

The “Blood Moon” Effect

During the advanced stages, the Moon takes on reddish or orange hues, a phenomenon known as the “Blood Moon.” This occurs because sunlight reaching the Moon passes through Earth’s atmosphere, scattering shorter wavelengths and leaving red tones dominant.

Special Activity at the Planetarium

The Galileo Galilei Planetarium is hosting a free evening event on Thursday 27 August, starting at 23:00. The activity includes telescopes and an accessible station for people with disabilities. The event’s execution will depend on the weather.
