On Wednesday, August 12, Belgium is set to experience a rare astronomical event: a significant solar eclipse where a remarkable 90 percent of the sun's surface will be obscured. This natural phenomenon, last seen in this magnitude in 1999, promises a spectacular experience for everyone in the country, especially in the province of Antwerp.
What is happening
The solar eclipse of August 12 is a partial solar eclipse, where the moon covers a large portion of the sun. This will result in a noticeable decrease in daylight and a unique celestial display. To safely observe this phenomenon, it is crucial to wear certified eclipse glasses. Without adequate protection, looking directly at the sun can cause severe and permanent eye damage. Various stores in the province of Antwerp still offer eclipse glasses for those who do not yet have them.
Safely viewing the sun
Urania Public Observatory and Planetarium Antwerp specifically advise using only eclipse glasses that comply with the ISO 12312-2 standard. Avoid using regular sunglasses or homemade filters, as these do not provide sufficient protection. Various local initiatives in Antwerp and its surroundings are organizing viewing days where experts will be present to provide explanations and ensure safe observation. The Royal Meteorological Institute (KMI) also emphasizes the need for correct protection and will disseminate additional information through its channels.

Background
Solar eclipses occur when the moon passes between the sun and the Earth, temporarily blocking sunlight. While partial eclipses are more frequent, a 90% obscuration is relatively rare, making it a special moment for astronomers and the general public. The Royal Belgian Institute for Space Aeronomy (BIRA) closely monitors such events and contributes to public understanding of astronomical phenomena. This event offers an excellent opportunity to appreciate the beauty and precision of our solar system. The Federal Public Service for Health also stresses the importance of eye safety during such events and will launch prevention campaigns in collaboration with local authorities, such as the municipality of Antwerp.
Astronomical context
Statbel, the Belgian statistical office, does not collect specific data on solar eclipses, but the cultural and educational impact of such events on the population is significant. The National Bank of Belgium (NBB) does not report a direct economic impact, but local trade, particularly the sale of specialized eclipse glasses, may temporarily increase.
What this means for Belgium
For Belgium, and specifically for the province of Antwerp, this solar eclipse represents an educational and fascinating opportunity. Schools and scientific institutions, such as the University of Antwerp, will likely organize events to highlight the phenomenon. It is a moment to inspire both young and old and to ignite their interest in science and astronomy. The municipality of Antwerp and other local authorities will also likely communicate about the best places to safely admire the solar eclipse and remind everyone of the importance of eye protection. HLN Antwerpen has already compiled tips for the region. The Flemish Region, through the Department of Environment, may also communicate on the aspect of light pollution and its impact on the observation of such phenomena. European directives, as laid down in EUR-Lex, concerning the safety of personal protective equipment (including eclipse glasses) are relevant and are controlled by the FPS Economy.
