How long does the annular solar eclipse last in Xiamen? Guide to the observation of annular eclipse on June 2 1 day.

The once-in-a-lifetime annular eclipse will be staged on June 2 1 this year, and this annular eclipse in Xiamen is the best observation point, lasting nearly one minute. Then let's introduce the observation guide of annular eclipse on June 2, 20221day, which is revealed by astrological knowledge.

How long does the annular eclipse last in Xiamen: nearly one minute? On June 2 1 day, the annular eclipse will come to the earth. Xiamen, which lasts nearly one minute, is one of the longest cities in Chinese mainland. It is understood that the last annular solar eclipse in Xiamen was on the morning of May 20 12, 2 1. Eight years later, the annular eclipse reappeared in Xiamen. This annular eclipse is the top priority of this year's astronomical phenomena. Although there is still more than a month, many netizens have begun to discuss the best observation scheme.

According to the observation guide of annular eclipse on June 2, 2022, Kloc-0, the selection standard of the observation site of annular eclipse is slightly higher than that of total solar eclipse: if you want to see beautiful annular eclipse, you must be as close as possible to the center of the annular eclipse belt, so that the moon shadow can be located in the center of the sun when eating. The "ring" of 3354 looks more regular; Although the total solar eclipse is more spectacular, as long as the observer is located in the total solar eclipse zone, he can enjoy the prominence, chromosphere, Bailey beads and corona indiscriminately.

The following are some precautions when observing the annular eclipse. There are thousands of astronomical phenomena. Safety first: 1. Observers must, must, must use qualified Budd's membrane glasses, or install Budd's membrane at the objective end of the telescope for observation. No sunglasses, smoked glass, snack wrapping paper or so-called "eyepiece Budd film" can be used to observe the solar eclipse! 2. Budd's film is really unprepared. We can use the principle of pinhole imaging to project sunlight through sunlight onto paper for observation. 3. Like the total solar eclipse, the annular solar eclipse also has five symbolic time points, namely the first loss, the first eclipse, the second eclipse, the first light and the last contact. During an eclipse, the relative motion between the moon and the sun is caused by the revolution of the moon, so you will find that the relative motion between them is very slow. A complete annular or total solar eclipse, from the first loss to the last contact, usually lasts for more than 2 hours. You can observe with a telescope. But again, a qualified Budd membrane must be installed at the objective end, and the Budd membrane must be fixed to ensure that it will not fall off during observation! 5. Compared with the hectic observation of total solar eclipse and light, the observation of annular solar eclipse is relatively easy. It is best to use Budd film during the whole observation. 6. As mentioned above, the observation point selection of annular eclipse is relatively strict, and observers should choose places as close as possible to the center of the annular eclipse zone. If you want to observe, you should pay attention to the weather forecast at least one week in advance. After all, you can't see the sun on cloudy or rainy days, so you can't see the solar eclipse.
