How to Make a Pinhole Projector to View the Solar Eclipse Amid Shortage of Glasses
NASA says safe solar viewers or indirect methods are needed, as looking directly at the partial eclipse can damage the retina.
- On Wednesday August 12, a partial solar eclipse will be visible across the British Isles, with up to 96% coverage in some areas.
- The Moon passes between the Sun and Earth without perfect alignment during partial solar eclipses, prompting the Health Security Agency to warn that reduced brightness can cause permanent eye damage without pain.
- With solar eclipse glasses in short supply across retailers, experts recommend safe indirect viewing methods like pinhole projectors made from cardboard, white paper, tape, scissors, and aluminium foil.
- Estimated peak times vary by location, ranging from 7.05pm in Edinburgh to 7.16pm in Cornwall, while the Royal Observatory Greenwich will livestream the event for those unable to watch outside.
- This event offers the most coverage seen in the British Isles since 1999; residents must wait until 2090 for the next total solar eclipse visible from the region.
