August 2026 lunar eclipse in Argentina: time, how to watch, and best viewing locations

Argentina's skies will host a significant astronomical event in late August 2026: a deep partial lunar eclipse. Occurring between the night of August 27 and the early morning of August 28, the phenomenon happens when Earth passes between the Sun and the Moon, casting its shadow on our natural satellite.

According to NASA data, the eclipse process begins with the penumbral phase at 10:24 p.m. on August 27. The partial eclipse, where Earth's shadow starts to cover the lunar surface, commences at 11:34 p.m. The peak of the event, when approximately 93% of the Moon's diameter will be obscured, is expected around 1:13 a.m. on August 28. The partial phase concludes at 2:52 a.m., with the entire eclipse ending at 4:02 a.m.

This lunar eclipse is notable for its ease of observation. Scientific communicator Adrián González from the Galileo Galilei Planetarium stated that no special equipment is needed, and the eclipse can be viewed with the naked eye, provided the sky is clear. Unlike solar eclipses, lunar eclipses pose no risk to eyesight. While binoculars or basic telescopes can enhance the viewing experience by revealing crater details, experts recommend seeking locations away from urban light pollution for the best possible observation, though the event will be visible nationwide under favorable weather conditions.

During the eclipse's maximum phase, the Moon will take on reddish hues, a phenomenon González explained as "atmospheric dispersion." Sunlight passing through Earth's atmosphere refracts and scatters, allowing red and orange tones to reach the Moon's surface. This effect is popularly known as a "Blood Moon," though technically it is a partial eclipse as the entire lunar disk is not obscured.

The Galileo Galilei Planetarium will host a free event on the night of August 27, starting at 11:00 p.m., offering telescope viewings supervised by staff and an accessible station for individuals with disabilities. This activity is contingent on weather conditions.
