Observation method of time range and duration of partial solar eclipse

Dear friends, have you noticed the partial solar eclipse today? But what are the main points of the partial solar eclipse, how long will it last and where can I see it? The following are introduced one by one to find out the cause of partial eclipse.

range

The lunar penumbra of this partial solar eclipse basically covered Northeast China and North China. As long as the weather is fine, you can see this partial eclipse when you run or walk your dog in the morning.

Time+duration

As shown in the above picture, this is the time of partial solar eclipse in various places. The partial solar eclipse began at 7: 34 Eastern Standard Time (Beijing time) and ended at 1 1 point 49. On that day, the sunrise in Changchun was 7: 14, the first loss (initial) was 7: 35: 37, the food intake (when the sun was most covered by the moon) was 8: 48: 30, and the last contact (final) was 10: 09: 52. The food score (bite) was 0.456.

observational method

How to observe the partial solar eclipse must also be a problem that many friends are very concerned about. In fact, there are still many ways to observe partial solar eclipse.

One of the best tools for observing partial solar eclipse is welding goggles, followed by X-rays taken by hospitals. When watching the partial solar eclipse, you can use Budd's thin-film solar observation mirror, which is an eye dedicated to observing the sun. Daily sunglasses or sunglasses are only used to observe the surrounding scenery in the sun, and cannot be used to look directly at the sun. Also, you can't use unqualified sun observation glasses and filters, because these unqualified products can't block ultraviolet rays, so when you watch the profit and loss changes of the sun for two hours in a row, your eyes will be very serious to the sea.

At school, students can also make pinhole projection boxes. Use a carton with a length of 1-2 meters, open a hole about 10 cm in the center of both ends, stick the hole on the upper end with tin foil, and then stick a pinhole in the center of the tin foil with a needle; Stick the white translucent paper on the hole at the other end, and then test it in the sun to see if it can produce a circular image of the sun on the translucent paper. Note that you can't directly observe the sun through a pinhole with the naked eye.

You can also use a telescope to project, observe the solar eclipse through a telescope, or use a camera, but you must have a filter. Observing the solar eclipse directly from the viewing frame will also hurt your eyes.

At the beginning of this eclipse, the sun is near the horizon in most areas, so you can use the landscape to keep pace with the partial eclipse. Pay attention to the telescope and solar filter shooting!
