Solar Eclipse

On August 12, 2026, the astronomical event of the year will take place. An exceptional solar eclipse will be partially visible from mainland France a few minutes before dusk. On the top of the fort du Mont-Bart, the occultation will be close to 90%. A magnificent spectacle, which the Montbeliard astronomy club invites you to observe safely.

⚠️ Even a heavily obscured Sun low on the horizon remains dangerous to observe without adequate protection.
