Watch a solar eclipse safely

To look directly at the Sun, use eclipse glasses that conform to ISO 12312-2 and are in good condition. Ordinary sunglasses do not provide enough protection.

You may look at the Sun without glasses only during totality at your observing location, when its disc is completely covered by the Moon. Put them back on as soon as the Sun begins to reappear. During a partial or annular eclipse, eclipse glasses remain necessary for any direct viewing.

Do not use binoculars, a telescope, a camera, or any other optical instrument unless it is fitted with a suitable solar filter placed in front of the optics. Eclipse glasses are not sufficient in this case.

The information and times shown are provided for guidance only. Each observer must check local conditions and follow the applicable safety guidelines.
