Precautions for observing a total solar eclipse, and a complete set of precautions for observing a t

No, there is not enough transparency

It doesn't seem to be transparent enough to use carbon paper, so you can't see the sun.

Observing a total solar eclipse, you can't directly look at the sun, and if you look at the powerful sunlight directly, it will be extremely harmful to the eyes and may cause blindness.

The best tool for observing a total solar eclipse is, of course, a professional solar eclipse scope. If not, you can also use the best film, waste floppy disks, protective glasses for electric welding, blackened glass, or you can use the small hole imaging method to use the same small hole on the paper to see the image of the sunlight projected on the ground through the small hole. As well as dripping ink into the water in the basin to make it black, **sun shadow, etc.

An annular solar eclipse is a rare astronomical spectacle, but looking at a beautiful annular solar eclipse directly can damage your eyesight, so how can you safely observe an annular solar eclipse?

Astronomical phenomena are beautiful, but we can't ignore the safety hazards while making observations. For example, due to solar eclipses, the temperature will change, the earth's magnetic field will change, and the day will suddenly darken. As a result, some animals are not adapted to their physiological habits, such as dogs, cats and other pets should be leashed to avoid livestock panic and injury incidents.

Well, come onKnowledge of horoscopesTake a look at the total solar eclipse for a list of precautions.

1. It is strictly forbidden to disguise feudalism during the period of natural phenomena, maliciously deceive the masses, and undermine the unity of the nation and the state.

2. Do not be in other dangerous places such as streets and roads, so as not to pay too much attention to the danger of life caused by the eclipse, and pay attention to safety when you are on the balcony to avoid falling downstairs.

3. Due to the temperature caused by the solar eclipse, the earth's magnetic field changes, and the day is darkened. As a result, some animals are not adapted to their physiological habits, such as dogs, cats and other pets should be leashed to avoid livestock panic and injury incidents.

Observe a total solar eclipse and do not observe it directly.

Medical experts point out that "solar retinitis", in which the macula of the retina is burned due to ultraviolet and infrared rays that look directly at the sun for a long time, is almost impossible. The macula of the retina is the most sensitive part of the retina, which allows light to be concentrated and the image clear. Once burned, the retinal macula will never recover.

You may not feel it when you get burned, but you will react a few hours later, and in severe cases, you will lose sight. For this reason, the first thing to note during a total solar eclipse is that you should never look directly at the sun with the naked eye or any optical device (such as a telescope, etc.)!

This is not just a suggestion, but a very serious warning. How can we avoid some accidents? Here are a few ways to do it.

1) Quick and easy methods of observation.

In fact, the recommended practice is to use just two blank sheets of paper. One piece of white cardboard is used as a screen, and a pinhole is poked in the other cardboard, holding the pinhole cardboard up as far away from the screen cardboard as possible. The farther apart the two cardboards, the larger the image formed.

Of course, there is an easier way, you only need the help of your own hands, raise your hands up, and the fingers are perpendicular to each other, cross and overlap, so that the hands form a net with many small holes, which can be used as simple imaging holes.

2) Buy observation glasses or lenses.

Protective glasses require a special pair of glasses. There are glasses with this special sun observation protection lens on the market, ** about 5 yuan.

You can't make your own goggles, it's very dangerous.

3) Take a basin of water (a small cup is fine) and drip a relatively large amount of black ink into the water, which can be observed in the water during a solar eclipse. (Planar Mirror Imaging).

Safe method of a naked** solar eclipse.

The easiest way is to find a piece of glass, apply some ink or blacken, and use them to eclipse the sun, and your eyes will be protected from harm.

It is also possible to use the black and white film that has been used as a filter for observation. The method is to pull out the soft film and expose it to sunlight for about 30 seconds, and then allow sufficient time for development and fixing. Stack two (not single one) negatives on top of each other, and then clamp them in the middle with a hard cardboard frame, so that they can be used to use the sun.

Telescope observations.

Binoculars that are generally used to observe landscapes are small in size, easy to carry, and have a wide field of vision, easy to find targets, and are also relatively cheap, which is one of the ideal tools for observing solar eclipses. Thank you.
