Briefings

Researchers in Spain are preparing for a total solar eclipse on August 12, 2026, using portable telescopes and cameras to study the sun's corona. Professor Miloslav Druckmüller, a mathematician specializing in solar wind, is leading the effort from Pico Trigaza mountain, where he and his doctoral students monitor the event. The team aims to capture Baily's beads and track iron ion dispersal during the 25-minute totality window, though they face cloud cover and limited time. Druckmüller notes that while he has never enjoyed the actual eclipse, the mathematical and technical challenges remain high stakes for understanding solar physics.

Key points

• Miloslav Druckmüller, a professor of mathematics at Brno University of Technology, led a group of doctoral candidates to Spain to photograph a total solar eclipse on August 12, 2026.
• The team uses eight astrocameras equipped with spectral filters to analyze iron ionic species and track heat distribution in the sun's corona during the 25-minute eclipse window.

Context

Miloslav Druckmüller is a leading figure in solar eclipse photography, having led expeditions to Hungary and Iceland. His team in Spain aims to study the sun's corona using custom-built optical instruments and image-processing techniques developed over decades. The event occurs on the 12th day of August, with the moon's shadow expected to obscure the sun completely, revealing the corona's delicate structures.

Limitations

Evidence is limited to a single Spanish expedition; Iceland and Hungary teams had better viewing conditions but were clouded. Druckmüller states he has never enjoyed the actual eclipses, only the preparation. The 2026 eclipse is a composite sequence of photographs, and the 107-second window for data collection is a fixed constraint.
