A rare total solar eclipse will be visible from parts of Spain, Portugal, Iceland, and northern Russia on Wednesday. Northern U.S. states will see a partial eclipse. Special eye protection is required.
On Wednesday, a total solar eclipse will sweep across parts of Europe, with Spain set to witness its first full eclipse from the mainland since 1905. According to astronomers, the path of totality will include Iceland, Greenland, northern Russia, Spain, and a section of Portugal. In these areas, the moon will completely obscure the sun for a brief period, creating a rare astronomical spectacle.
For Spain, the event is especially significant. In León, totality is expected to begin at 8:28 p.m. local time and last for two minutes, while in Reykjavík, Iceland, the total eclipse will start at 5:48 p.m. local time. The European Space Agency notes that this marks the first time in over a century that mainland Spain will experience a total solar eclipse, making it a major event for both residents and scientists.
Meanwhile, northern regions of the United States, stretching from Alaska to North Carolina, will observe a partial solar eclipse. In these areas, the moon will only partially cover the sun, resulting in a crescent-shaped sun. For example, in Washington, D.C., the partial eclipse is set to begin at 1:17 p.m. ET, with up to 4% of the sun's surface obscured, according to NASA.
Authorities and experts are urging the public to take safety precautions. Viewing the eclipse without proper protection can cause severe eye damage, including burns and permanent vision loss. The American Academy of Ophthalmology stresses that only certified eclipse glasses or handheld viewers with special filters are safe for direct viewing. Regular sunglasses do not provide adequate protection, even during a partial eclipse.
Beyond the public interest, the eclipse presents a valuable opportunity for scientific research. NASA will deploy high-altitude balloons and a jet to study how the temporary darkness affects Earth's atmosphere. The agency highlights that total eclipses allow scientists to observe the sun's corona in ways not possible at other times, offering insights into solar activity and its impact on our planet.
In Spain, the event has prompted both excitement and logistical challenges. Some municipalities have adjusted or cancelled public viewing events due to safety concerns, as seen recently in Madrid, where wildfire risks led to the cancellation of several gatherings. Only 30 out of 52 towns in the region submitted emergency plans, reflecting the heightened attention to crowd management and public safety. More details on these local measures can be found in this report on how Madrid municipalities responded to eclipse-related fire risks.
Looking ahead, the next partial solar eclipse visible from parts of the U.S. is scheduled for August 2, 2027, with totality passing over Spain, the Middle East, and North Africa. Another total solar eclipse will cross the contiguous United States on August 23, 2044. For now, the upcoming eclipse stands out as a rare and memorable event for Spain and much of Europe, combining public fascination with scientific opportunity and a renewed focus on safety and preparedness.
Solar eclipses occur when the moon passes between the Earth and the sun, either partially or fully blocking the sun's light. Total eclipses are rare for any given location, often separated by decades or even centuries. The phenomenon not only captivates skywatchers but also provides a unique chance to study solar and atmospheric processes under unusual conditions. As the date approaches, authorities continue to remind the public to plan ahead, use proper eye protection, and follow local guidance to ensure a safe and rewarding experience.
