# August 2026 solar eclipse preparations in Europe > Live situation record from CLSTR: https://clstr.news/situations/august-2026-solar-eclipse-preparations-in-europe > Updated: 2026-08-07T10:29:10.000Z. Sources: 148. Developments: 2. A total solar eclipse on August 12, 2026, is prompting technical and logistical preparations across Europe. The path of totality is expected to traverse the Arctic Ocean, Greenland, Iceland, and northern Spain before moving toward the Balearic Islands. While specific regions such as parts of Galicia and Catalonia will experience totality, other areas will see a deep partial eclipse. Energy grid operators, coordinated by the European Network of Transmission System Operators for Electricity (ENTSO-E), are preparing for a significant dip in solar power generation. Estimates suggest photovoltaic output could decrease by up to 9.7 GW between 19:15 and 21:30 CEST, provided skies are clear. Spain and Germany are projected to face the most substantial impacts; specifically, Spain's Red Eléctrica anticipates a potential reduction of up to 5 GW. To maintain grid stability, operators have activated a dedicated task force to monitor the situation and avoid planned maintenance. In Spain, authorities are preparing extensively for the influx of visitors. The Spanish Guardia Civil is deploying over 24,000 personnel to oversee more than 660 observation points. Localized safety measures have been enacted, such as the 24-hour closure of El Javalon mountain to vehicular traffic in Jabaloyas to manage environmental risks and public safety. In Catalonia, approximately 30 official locations have been identified to facilitate safe viewing. Scientific interest remains high, with researchers investigating atmospheric phenomena like shadow bands. Scientists are also utilizing historical data, such as records from a 1905 eclipse in Catalonia, to contextualize the event. Observers should anticipate meteorological changes, including a temperature drop averaging approximately 5 degrees Celsius. In Germany, a partial eclipse is expected with 84% to 93% solar coverage. Experts remind observers to use certified solar protection to prevent eye damage. ## Claims - In Germany, observers will see a partial eclipse with up to 90-93 percent solar coverage.
