When observing a total solar eclipse, please be sure to observe the following precautions to ensure the safety of observers and equipment.
1. Direct observation without naked eyes or optical equipment
When watching a total solar eclipse, first of all, you must pay attention to one thing: Never look directly at the sun with naked eyes or any optical equipment (such as a telescope, etc.)! This is not just a suggestion, but a very serious warning. If you observe directly with the naked eye, the extremely strong sunlight will not only make it impossible to observe at all, but may even burn your eyes. When observing with optical equipment, because the magnifying glass in the optical equipment focuses the sunlight to a very small point, the energy at that point is considerable, which may damage the observer's retina, or even cause blindness in severe cases. The retina does not feel pain, so even if it is burned, you will not notice it. This is especially important to note. When observing, it is best to use eclipse glasses that filter out dangerous light. Observe for about 3 minutes and let your eyes rest. This is safer.
2. Pay attention to the potential dangers of optical equipment
When observing a solar eclipse using optical projection, do not place your hands or any flammable objects near the eyepiece. Focused sunlight can cause fire or damage. At the same time, the telescope must be cooled from time to time. Working in the sun for a long time may cause the eyepiece to overheat and cause the lens to break.
3. Pay attention to your physical condition to prevent heatstroke
The temperature is high in summer, and you are at risk of heatstroke if you stay outdoors in the sun for a long time. Moreover, if you keep looking up at the sun for a long time, the blood flow in the head will lag, and there is also a risk that your physical condition will deteriorate. When observing, be prepared with a hat and cold drinks, go to a cool place to rest from time to time, etc. The most important thing is to protect your body.
4. Pay attention to personal safety
This solar eclipse occurs during the summer vacation. Young students should try their best to participate in group viewing activities organized by the school. If they act alone, they must be accompanied by their parents. Watch the total solar eclipse with the guidance of When selecting an observation location, in addition to considering the observation effect, you should also pay attention to potential safety hazards. It is recommended to watch the total solar eclipse on the balcony of your home, in the garden or in an open space in your community. Do not go to crowded places to prevent stampede accidents. Do not climb high places in order to find a good observation angle to avoid losing your footing and falling.
