Excitement is building across Ireland ahead of the country’s first partial solar eclipse since 2015, with hundreds of people already queuing up to get their hands on specialist viewing glasses before the big event.
The last time Irish skies offered up this kind of spectacle was nearly ten years ago, so it is little surprise that people are keen to make sure they catch it properly this time around. Demand for the protective eclipse glasses has been strong, with queues forming at outlets stocking the specialist eyewear.
Looking directly at the sun without proper protection is genuinely dangerous, capable of causing serious and permanent damage to eyesight even during a partial eclipse. Regular sunglasses simply do not cut it. The specialist glasses required are thousands of times darker than ordinary shades and are specifically designed to filter out the harmful radiation that can burn the retina.
Astronomers and science communicators around the country have been urging people to plan ahead and source the correct glasses before the day arrives, warning that stocks can run out quickly once interest peaks. Schools and astronomy clubs have also been getting involved, organising viewing events and educational sessions around the eclipse.
A partial solar eclipse occurs when the moon passes between the earth and the sun but does not completely block out the solar disc. From Ireland, viewers will see the moon take a noticeable bite out of the sun, creating that distinctive crescent shape that makes eclipses so striking to watch.
Ireland’s position on the edge of the Atlantic means the country gets a decent view of Atlantic weather systems rolling in, which is both a blessing and a curse when it comes to eclipse watching. Cloud cover has ruined many an Irish attempt at stargazing and eclipse viewing over the years, so plenty of people will be keeping a close eye on the forecast as the date approaches and hoping the weather plays ball for once.
For those who missed the 2015 eclipse, that event drew huge crowds across the island, with people gathering on hillsides, beaches and in open fields to watch the spectacle. Schools had organised special viewings and the atmosphere on the day was described by many as genuinely memorable, even where cloud cover partially interrupted the show.
Astronomy Ireland and other groups have been active in the lead-up to this eclipse, providing guidance on safe viewing and sharing information on where and when the eclipse will be most visible from different parts of the country. The further north and west you are in Ireland, the better the view is generally expected to be.
For anyone who cannot get their hands on the glasses in time, there are alternative ways to watch safely. A simple pinhole projector can be made at home using cardboard, allowing the image of the eclipsed sun to be projected onto a surface without ever looking directly at it. It is a low-tech solution but it works well and has been a go-to option for eclipse watchers for generations.
Live streams will also be available online for those who end up stuck indoors or under heavy cloud, with various science organisations planning to broadcast footage from locations around Ireland and beyond.
Solar eclipses have fascinated people for thousands of years and even in an age where the science behind them is well understood, they still manage to draw crowds and spark genuine wonder. There is something about standing outside and watching the light change, feeling the temperature drop slightly and seeing the sun partially disappear that no amount of explanation quite prepares you for.
If you are planning to watch, the message from experts is simple. Get the right glasses, check the forecast, find a spot with a clear view of the sky and enjoy one of nature’s more impressive shows.
