MADRID — A total solar eclipse crossed Iceland, Greenland and northern Spain on Wednesday, drawing millions of skywatchers to the first path of totality over mainland Europe since 1999. Astronomers and tourism officials had prepared for months for the event.

The eclipse reached totality across a band stretching from Greenland through Iceland and into Spain, passing over cities including Zaragoza, Bilbao and Valencia. The Spanish government's astronomy agencies and civil protection authorities issued guidance on safe viewing, warning against looking at the sun without certified solar filters.

Local officials reported hotel occupancy near capacity in many towns along the path. The astronomical event coincided with a new moon, which some spiritual and wellness communities highlighted as carrying particular significance.

Coverage in lifestyle and astrology outlets framed the eclipse as a moment for reflection and renewal, while scientists at observatories emphasised research opportunities to study the sun's corona.

Spain's tourism sector anticipated a substantial economic boost, with regional authorities in Aragon and the Basque Country organising public viewing events and distributing eclipse glasses. Retailers reported strong sales of protective eyewear in the days leading up to the event. Cloud cover threatened visibility in some coastal areas, prompting many observers to travel inland.

The 2026 eclipse was widely anticipated as a precursor to a second European total eclipse in August 2027, which will cross southern Spain and North Africa. Astronomy groups said the back-to-back events represented an unusual opportunity for the continent.
