- Spanish regions and municipalities have set up official observation points and are distributing hundreds of thousands of certified ISO 12312-2 eclipse glasses to reduce eye-injury risk.
- Transport operators have scheduled special and reserve trains and road agencies will deploy extra lighting and traffic measures to handle large, late-afternoon movements to viewing sites.
- Portugal’s grid operator REN has estimated a temporary loss of about 450 MW of photovoltaic output and is preparing measures to compensate for that reduction during the event.
- NASA will livestream the eclipse and run scientific flights and high-altitude balloon campaigns to image the solar corona while national observatories and apps such as the IGN visualizer and Eclipsi.info guide site selection and visibility checks for the public.
