As long as it doesn't block the sun in the southeast.
CCTV 10 news channel Oriental TV will broadcast live.
The specific observation time is as follows
Initial loss time 8 20 28
Eating time 9 35 59
Last contact time 10 58 48
Every time there is a total solar eclipse, I don't know how many people will just aim the camera at the sun during the non-total solar eclipse stage.
Medical experts point out that "solar retinitis" caused by long-term direct exposure to the ultraviolet and infrared rays of the sun is almost incurable. Macula is the most sensitive part of retina, which makes light converge and makes the image clear. Once burned, the macula can never be recovered. Pointing cameras, telescopes and other observation instruments directly at the sun will not only damage the lenses in the instruments, but also directly burn the retina by the optically concentrated sunlight.
In order to reduce a lot of ultraviolet and infrared rays in sunlight, please don't use it.
Sunglasses: This is one of the most dangerous methods to observe the total solar eclipse, and it is also one of the most easily misunderstood methods. Sunglasses and sunglasses are not specially designed for observing the total solar eclipse. Wearing sunglasses to directly observe the total solar eclipse will hurt your eyes.
Exposure film: This method has been used to observe the total solar eclipse before, but it is not recommended, because everyone's film production level and exposure are different, and the observation safety cannot be completely guaranteed.
Candles painted with black glass: this is also an early indigenous method, but there are still problems. Due to the uneven blackening degree and glass thickness, the observation safety cannot be completely guaranteed, and this method is not recommended.
Floppy disk magnetic core: same as candle blackened glass.
X-ray: this method has not been fully demonstrated and confirmed, and it is not recommended to everyone.
Water splashed with ink: Although the water splashed with ink becomes a black background, it will still reflect more sunlight to the observer's eyes, which will still be harmful to the eyes. Not recommended.
For the sake of eyesight safety, please use.
Special observation mirror: (or self-made observation equipment for professional dimming membrane filtration such as "Bader membrane")
Small hole imaging method: Punch a small hole in the paper with a needle, and observe the total solar eclipse through the projection of the small hole on another paper or other interfaces; In addition, two fingers can cross to form a small hole for observation.
Telescope projection observation method: after the sun passes through the telescope, it will be projected on the ground, and the total solar eclipse will be watched through observation projection. But don't watch the total solar eclipse directly through the telescope, which will lead to blindness in severe cases.
Welding goggles: There is a shop that specializes in welding goggles. However, it should be noted that welding goggles are different from sunglasses, and sunglasses cannot be used to observe the total solar eclipse.
On July 22nd, 2009, are you ready to watch the once-in-a-century total solar eclipse?
When observing the total solar eclipse, you should choose sunny areas as much as possible and pay attention to the safety of your eyes. Because the sun's light is one million times stronger than moonlight, it can't be seen directly with the naked eye or through a telescope without dimming equipment, otherwise it will easily cause retinal damage and even blindness. During the partial eclipse, it is safer to wear a pair of glasses for observing the total solar eclipse, or use a basin filled with ink to watch by reflection. When observing the total solar eclipse with a telescope, you must add a filter in front of the eyepiece or detector to avoid burning your eyes. During the total solar eclipse, you can watch it directly with the naked eye. Before shooting with a telescope, you should take a dimmer or filter.
