Clear spells set to reveal partial lunar eclipse on Sunday

After an unsettled start to Sunday, clear spells are expected to develop across Ireland in the late afternoon and early evening, giving skywatchers the chance to catch a glimpse of a partial lunar eclipse.

The September full moon, known as the “Corn Moon” for its association with the harvest season, will take on deep red hues during the eclipse, earning it the nickname “Blood Moon.” The phenomenon occurs when the Earth moves between the sun and the moon, casting a shadow that tints the lunar surface.

While the eclipse will be fully visible across Asia, Australia and much of Africa, observers in Ireland will see only the final stages as the moon rises. In Dublin, the eclipse officially begins at around 5.30pm and peaks shortly after 6pm, but moonrise occurs at 7.57pm. As the moon emerges above the horizon, it will gradually brighten, offering a brief but striking view.

Local conditions will play a key role, with the best observations expected from east-facing locations under clear skies. Experts suggest binoculars or a small telescope to enhance the experience, though the event is safe to watch with the naked eye.

The September lunar eclipse follows a busy autumn for skywatchers, including close approaches of Jupiter and Saturn and the recent Perseid Meteor Shower.

This partial eclipse is the last visible from Ireland in 2025, with the next opportunity not until 2026. The next total lunar eclipse over Ireland will be on New Year’s Eve in 2028.
