    Thankfully it is not difficult to protect yourself. You need a filter that will let less that one part in a thousand to pass (do not bother with the exact number, just go with something CE certified). These are very cheap to produce, and since you are likely to need them for less than a hour, they are usually mounted on flimsy paper frames. As long as you don't break them, they are fine.What is NOT fine are sunglasses. They let way too much light through. Even worse, avoid binoculars&co like the plague.Another very safe option is what is called a pinhole camera. Take an opaque screen (I have successfully used cereal boxes before), make a small hole in it, and let the sun shine through it. Beyond (in the shadow of the screen) you will see a very crisp image of the sun, which is very safe to watch. If you want to be romantic (and you live in a place that allows you to do it), you can sit below a tree with a well-developed canopy. The small spaces between the leaves will each behave like a pinhole camera, and you will get tens or hundreds images of the eclipse on the grass. Very pretty ;-)2/2

    @antoinechambertloir Oviedo, c’est presque la côte. Un avantage et deux inconvénients : – l’éclipse, c’est un chouïa plus tôt, le soleil est un peu plus haut.– c’est la côte, donc j’imagine, plus de monde (mais je ne suis pas sûr : quand on se rapproche de Madrid, on a plus de gens qui viennent de Madrid pour voir l’éclipse mieux qu’à Madrid)– surtout, et c’est le risque principal, des « entrées maritimes » sont plus probables qu’à l’intérieur, je pense. Et s’il y a des nuages, c’est foutu. @YannC
