An annular solar eclipse will be observed in Brazil on 10/14/23, but observing the show requires special care so as not to cause eye damage
On October 14, 2023, a Annular solar eclipsea splendid natural astronomical spectacle that can be observed in Brazil.
But in a narrow band covering several Northeastern and Northern states, it will be possible to see the annular solar eclipse in its full form, which will look like a bright ring around a dark disk.

The appearance of the eclipsed sun will vary depending on where each person is located. In most of Brazil, the view of the eclipse will be like “biting into an apple, where only a portion of the solar disk will be obscured.”

Very important: eye protection when viewing the eclipse
Observing a solar eclipse requires great attention. It is important to highlight that direct observation of the Sun or the use of non-specialized equipment can cause irreversible damage to sight and even, in extreme cases, blindness.
It should NOT be used X-ray plates, photographic films, smoked glass, reflections in water tanks and other artefacts for observing the Sun.

And how to observe?
There are two very safe ways to observe a solar eclipse: directly or indirectly. Let’s understand them and apply eclipse observation in practice:
1st way: directly: A number 14 welded glass lens is for viewing the Sun directly. Since the number 14 lens is hard to find, you can use number 12, but never below that number. The unit cost of this welding lens is R$15.50 (Mercado Livre), but in a physical construction store you can find it at a much cheaper price. Figure 3 shows a photo of the welder’s glass lens and how we observed the eclipse.
Using a welding filter to observe the solar eclipse
To observe the solar eclipse using the soldering glass lens it is necessary to carefully follow the steps:
1st – lower your head and place the welding glass in front of your eyes;
2nd – raise your head and observe the eclipse for up to ten seconds and;
3rd- lower the head and remove the welding glass.
It is very important to underline that, if the observer removes the glass lens in front of his eyes, while observing the Sun (step 2), he will definitely feel pain in his eyes. For this reason it is essential to complete all steps, including step 3.

2nd way – indirectly: If the observer is afraid of observing directly, or is unable to obtain a welder’s glass lens, or even wishes to show the eclipse to a child, it is advisable to observe the eclipse indirectly.
There are several safe ways, but a simple and interesting way is to use a colander or colander equipped with furos in the shape of circles. In fact, you can use any object that has a circle-shaped hole, which can also be made on a sheet of paper with a simple needle puncture. Then just project it onto the floor and you’re done!
The following figure illustrates how to indirectly observe a partial solar eclipse using a colander.
