Overview
- The Moon's central shadow will cross much of northern Spain, producing short periods of totality near sunset on Wednesday, August 12, with the eclipse's global maximum occurring near Iceland at about 19:46 local time.
- Totality in Spanish locations will be brief and low on the horizon, with example solar altitudes at maximum of about 12° in A Coruña, 8° in Burgos, and 2° in Palma, while Madrid will see a very deep partial eclipse that will not reveal the corona.
- TriEclipse will deploy more than 200 volunteer observers across Spain to film animal and ecological responses using phones, trail cameras and professional gear, with organizers cautioning that changes may be subtle and data will require careful filtering.
- Iberia will operate a specially routed observation flight, IB1473, leaving Madrid at 18:45 on August 12 in an Airbus A321XLR that will carry Shelios researchers, transmit live via Starlink, and seek clearer views of the corona from cruise altitude.
- Medical and safety authorities stress that unprotected viewing can cause permanent eye damage and recommend ISO 12312-2 eclipse glasses and proper filters for cameras or telescopes, and officials warn that low sun angles and local weather or horizon obstacles may limit what the public can see and affect event planning.
