Total Solar Eclipse 2024 | When, Where, What, How and Why

Do not look directly at the sun. Please always double check that any eclipse glasses or camera lens/telescope filters you are using pass the ISO 12312-2 international standard and do not have any scratches on them by holding them up to a light in your house first (all you should be able to see through them is the filament of the light bulb).
