Sean Barraclough
Creator of Aurora Tonight
Web Developer · Dorset, UK
Sean Barraclough is a web developer based in Dorset, UK with a long-standing interest in space. He built Aurora Tonight during the current solar maximum after finding that existing aurora forecast tools were either too technical, too geographically generic, or simply outdated.
The site draws on data from NASA's DONKI database and NOAA's Space Weather Prediction Center to produce a location-specific forecast that updates every 30 minutes. His background is in software development rather than space science - his focus is on presenting authoritative scientific data in a form that is genuinely useful to people deciding whether to go out tonight.
He also built closeapproach.space, a near-Earth asteroid close approach tracker, from the same interest in making space science accessible.
Aurora Tonight uses space weather data from NASA DONKI and NOAA SWPC. The forecast updates every 30 minutes. Read more about why the site was built.
