Total Eclipse 2026
Totality at sunset over Cuéllar, Spain
On 12 August 2026 the Moon's shadow returned to mainland Spain for the first time in more than a century. Our expedition, led by Hamid D. Khodashenas (MrEclipse of Iran), observed totality from the walls of Cuéllar Castle in the province of Segovia, with the Sun only about 8° above the western horizon, and broadcast it live to audiences worldwide. It was Khodashenas's 17th total solar eclipse.

Field Notes
From his first total eclipse at Gahar, Lorestan, in 1999 to Zimbabwe, Antarctica, the Galápagos, the Sahara, the Arctic, the United States and Australia, every eclipse has marked another chapter in a journey of nearly three decades. In 2026 the destination was the historic Castle of Cuéllar, one of the finest sites on the path of totality.
What made this eclipse exceptional was its timing: totality came with the Sun hanging low in the evening sky, combining the blackened Sun, the delicate corona and the warm colours of sunset. The Sun set about 45 minutes later, still partially eclipsed.
From the heart of the path the team observed with professional astronomical and imaging equipment, joined by about fifty observers from the Segovian group Astronomía Cercana, and broadcast the event live on YouTube and Instagram so that people unable to travel could follow totality with scientific commentary.
“Cuéllar, with its ancient history and heritage, was our observing site for the total solar eclipse of August 12, 2026. The warmth and hospitality of the people of Spain, especially Carlos and his family, made these three days in Cuéllar truly memorable. This eclipse was my 17th total solar eclipse.”
