Obviously, this kind of event is not the same according to where we are. The partial eclipse will be the least visible in the south and in the east of the country, with barely 9.9% of the sun hidden by the moon in Nice or 16% on the side of Strasbourg.
Conversely, if you live in the north of France, know that 25.1% of the sun will be hidden by the Moon on the side of Nice. Finally, it is in the west of France where the phenomenon will be more important, on the side of Nantes (26.7%) and especially on the side of Brest (32.5%).
As a reminder, observing this event requires taking certain security measures. It is extremely dangerous to watch an eclipse without equipment, with the risk of losing your sight. You can provide you with eclipses for the occasion, glasses that are sold in particular in optical stores.
