Blood Moon to rise over Ireland next weekend

A total lunar eclipse of the September full moon will be visible in parts of the world on Sunday, September 7th, with Irish viewers set to witness the spectacle only in part as the moon rises.

Known as the “Corn Moon” because of its traditional link to the harvest season, the full moon will appear in deep shades of red during the eclipse, earning it the popular name “Blood Moon”. The phenomenon occurs when the Earth passes directly between the sun and the moon, casting a reddish shadow across the lunar surface.

The eclipse will be visible in full across Asia, Australia and much of Africa. In Ireland the moon will rise already partially in shadow, with the most striking phase of the eclipse having taken place below the horizon. Observers here will see the moon gradually brighten as it emerges from the Earth’s shadow during the early evening.

The eclipse begins at about 5.30pm Irish time, reaching its peak shortly after 6pm. However, moonrise in Dublin is not until 7.35pm, meaning only the closing stages will be seen. The precise view will vary depending on location and weather conditions, but experts recommend finding a clear vantage point facing east to catch the best sight of the reddened moon climbing into the night sky.

The event follows several astronomical displays this autumn, including close approaches of Jupiter and Saturn, and the Perseid Meteor Shower. Unlike solar eclipses, lunar eclipses are safe to watch without protective glasses, though binoculars or a telescope will enhance the view.

The September lunar eclipse is the last of its kind this year and the only one visible from Ireland until 2026.
