Wednesday’s rare event will bring totality to Greenland, Iceland, Spain and a corner of Portugal as authorities urge safe viewing and careful travel
A total solar eclipse will cross parts of Europe and the North Atlantic on Wednesday, 12 August, bringing complete darkness briefly to Greenland, western Iceland, much of northern Spain and a small area of northeastern Portugal. Most other European observers will see a partial eclipse. With the phenomenon occurring close to sunset in Spain, authorities are urging people to choose locations carefully, avoid unnecessary travel and use certified eye protection throughout every partial phase.
Where the eclipse will be total
The narrow path of totality will pass across the Arctic, northeastern Greenland, western Iceland and the Atlantic before reaching the Iberian Peninsula. According to the European Space Agency, Spain will contain the largest inhabited area of totality in Europe. The event will be the first total solar eclipse visible from mainland Spain since 1905.
A total eclipse occurs when the Moon passes directly between Earth and the Sun, completely covering the Sun’s bright surface for observers inside a relatively narrow corridor. The solar corona, the Sun’s outer atmosphere, becomes visible during this brief period. Outside the corridor, the Moon will cover only part of the Sun.
The maximum phase of Wednesday’s eclipse will occur near Iceland at approximately 19:46 Central European Summer Time. The longest period of totality anywhere along the path will last about two minutes and 18 seconds.
Across much of Ireland, the United Kingdom, France, Belgium, the Netherlands, Scandinavia and central Europe, the eclipse will be partial. The proportion of the Sun covered will depend on the observer’s exact location. In those areas, there will be no safe period for looking at the Sun without suitable protection.
Spain’s low evening Sun changes the view
Spain is situated near the end of the eclipse path, meaning totality will occur with the Sun already low in the western sky. Buildings, hills, trees and even slight changes in terrain could obstruct the event. A location with a clear western horizon may therefore matter as much as the distance travelled.
The Spanish National Geographic Institute’s official eclipse information provides local timings and visibility data. In A Coruña, the partial phase is expected to begin at 19:31, with the maximum at 20:28. Totality should last about 76 seconds, with the Sun approximately 12 degrees above the horizon.
In Burgos, the eclipse begins at 19:33 and reaches its maximum at 20:29. Totality is expected to last about 104 seconds, but the Sun will be only eight degrees above the horizon. In Palma, the maximum is expected at 20:32, when the Sun will be just two degrees high and close to setting.
These differences make last-minute journeys risky. Moving a short distance may improve the view, but heavy traffic can leave travellers stranded without a clear horizon or access to an official viewing area.
Certified viewers are essential
Ordinary sunglasses, regardless of how dark they appear, do not provide adequate protection for direct solar observation. Viewers should use eclipse glasses or handheld solar filters conforming to the EN ISO 12312-2:2015 standard. Products sold in the European Union should also carry the appropriate CE conformity marking and identify the manufacturer.
Certified protection must remain in place during every partial phase. Only observers located inside the path of totality may remove it, and only after the Sun has been completely covered. The viewers must be replaced immediately when the first bright sunlight reappears.
Cameras, telescopes and binoculars require correctly fitted solar filters placed in front of their optics. Looking through magnifying equipment while wearing eclipse glasses is not safe because concentrated sunlight can damage both the filter and the eye.
Children require close supervision, particularly during the transition into and out of totality. People without certified protection can still follow the event through indirect projection methods or official broadcasts, including ESA’s English-language transmission from the Javalambre Astrophysical Observatory in Teruel.
Traffic and accessibility shape the event
Spain has prepared an exceptional traffic and civil-protection operation. A government economic assessment projected approximately 446,700 additional visitors in affected provinces during the week of 10 to 16 August. Authorities have warned that congestion could be severe and prolonged before and after the eclipse.
Travellers have been advised to use public transport where possible, choose designated observation areas and avoid stopping on road shoulders. An eclipse seen from a nearby, prepared location is safer than one pursued through congested roads at the last moment.
The official Spanish viewing tool has been designed to meet WCAG 2.1 AA accessibility standards and includes assisted navigation and audio features. That work recognises that access to a major public science event should not depend entirely on sight, private transport or specialist knowledge.
A shared exercise in public science
The eclipse offers European scientists an unusual opportunity to explain solar physics to a mass audience. ESA missions including Solar Orbiter and Proba-3 study the Sun, its corona and its effects on Earth continuously, while Wednesday’s alignment will make part of that science visible without specialist equipment.
It is also an exercise in trusted public communication. The European Times has previously examined how confidence in science depends on institutions explaining evidence, uncertainty and risk clearly. For the eclipse, that means distinguishing totality from a partial eclipse, correcting unsafe advice and ensuring official information reaches residents and visitors in accessible forms.
Wednesday’s event begins a remarkable sequence for the Iberian Peninsula. Another total solar eclipse will cross Spain on 2 August 2027, followed by an annular eclipse on 26 January 2028. Yet each event will have a different path, time and safety context. For millions of Europeans, this week’s eclipse will remain a rare chance to witness daylight briefly give way to the Moon’s shadow.
