Advice for the solar eclipse

Here you will find all the recommendations you shouldn’t ignore to have a unique view during the eclipse of 2019.

Check the solar eclipse sequence and its phases

This July 2, there will be a solar eclipse that occurs when the moon passes between the earth and the sun. Its different phases show how the sun’s image gradually goes from partially to totally hidden. It is believed that the totally hidden image of the sun can only be observed in the Umbra strip between the Atacama and Coquimbo regions. This total solar eclipse (the sun will be 100% covered) lasts a maximum of 2 minutes and 34 seconds. This is how AURA, the Association of Universities for Research in Astronomy, graphs it. (Ask for permission) Look over the solar eclipse sequence and its phases.

How to safely watch a solar eclipse

  • Do not look at the solar eclipse directly, always use special goggles with filters that safely reduce sunlight and block the ultraviolet and infrared solar radiation. Make sure you buy them in a formalized business to ensure they have adequate certification. A few pages where you can find sunglasses are and
  • Before putting on your special glasses, check that the filter is in perfect condition, without damages, scratches or perforations, and that it is less than 3 years old.
  • You must wear your glasses before looking at the sun and before the solar eclipse begins. How? Follow these steps: look at the ground, put on your eclipse glasses and look at the sun only when your eyes are covered.


  • In places where there will be a partial solar eclipse (less than 99%), glasses should be used at all times. The only exceptions are the umbra zones, where there will be a total solar eclipse (Atacama and Coquimbo regions). In these areas, the moon completely blocks the bright sun and the sky becomes quite dark. There will be a brief phase of ” totality” when you will not see be able to see anything through the glasses. At that time, you could remove them, without harming your eyes, and see the crown. Be ready to wear them again once the moon has fully passed and the sun begins to reappear.

Know the alternatives to watch the solar eclipse in Chile without special glasses

  • An alternative method is the pinhole projection: cross your extended and slightly open fingers of one hand over the extended and slightly open fingers of the other. With your back to the sun, watch the projection of your hands’ shadow on the ground closely. The small spaces between your fingers will project a grid of small images on the ground, showing the sun as a half moon during the partial phases of the eclipse.


  • Another safe option is to use a pinhole type viewer made from a cereal box, aluminum foil and tape. It’s a fun craft to make with your children!
  • A secure pinhole projector with binoculars can also be useful to watch the eclipse with a large group. This is a way to enhance what you see through a pinhole viewer.

How to make an eclipse observatory or a homemade pinhole projector

  • It’s very simple. You just need some thick paper or cardboard. At its center, use a pin to drill a small hole and place a second piece of cardboard on the floor to project the eclipse onto. Stand with your back to the sun and try not to cover the hole in the cardboard you are holding down on the ground with your head.
  • You must align the projector well and you will see a perfect circle on the other piece of cardboard that is on the floor. The circle’s edges will sharpen as you approach or move the projector away from the ground. During a partial eclipse, the circle will shrink and become a crescent and during a total eclipse, it will become an O with thin edges.
  • Although the image that is projected is small, it is an ideal alternative if you are accompanied by children.

What you should not use to watch a solar eclipse

It is not recommended to watch eclipses through a normal camera, telescopes, binoculars, sunglasses, any kind of glasses, tinted windows, exposed color films or other unfiltered optical devices. None of these elements protect your eyes since the ultraviolet and infrared waves can pass through these objects and cause damage.

Recommendations for photographing an eclipse

When you look at or photograph the partial phases of a solar eclipse, you should use filters. “Full opening” and “off-axis” filters are safe for cameras and telescopes. These filters fit over both the front end of the telescope and the camera lens.
The full opening solar filters are preferred. This is because the filter covers the front of the telescope completely and the entire mirror or lens is used. It will not be necessary to refocus the telescope or camera lens when you remove the filter at the beginning of the “totality” phase or when you put it back on after this phase is over.

Interesting techniques to watch the eclipse

Did you know? Trees can be very helpful when watching an eclipse.

Try looking at the images that are projected from the sun onto the ground through the space between the leaves. You can also use a white cardboard sheet to capture the images and achieve a great visual experience. You only have to cut a small square in the paper, stick a piece of aluminum foil to it, prick a hole with a pin and reflect the eclipse from the intervened paper to another where it is projected. An interesting fact is that an eclipse can confuse animals, causing them to make strange sounds in the dark.
