Aug. 12, 2026 eclipse will deliver a one-of-a-kind corona snapshot

TL;DR
During the Aug. 12, 2026 total solar eclipse, the sun’s corona will briefly become visible and will reflect the solar magnetic activity of Solar Cycle 25, meaning no two eclipses look the same. Observers may see prominences along the edge and, with luck, a CME snapshot, but the exact corona depends on sunspot activity in the days around totality and viewing conditions.
