A total solar eclipse occurred on July 22, 2009, and an annular solar eclipse occurred on May 28, 20 12. The next time will happen on March 20, 2034, in the mountainous area of northern Tibet, but it is basically no man's land. In addition, on September 2, 2035, another total solar eclipse occurred in northern China, lasting for 1 min 29 seconds.

Total solar eclipse is a kind of total solar eclipse, which occurs in the range of about18 near the intersection of the ecliptic and the ecliptic. When a total solar eclipse occurs, the ionosphere in the upper atmosphere will change accordingly because the moon blocks solar radiation.

This will temporarily interfere with the medium-wave and short-wave communication in which the signal needs to be reflected by the ionosphere, while FM broadcasting, mobile phones and wireless Internet access using ultrashort waves will not be affected.

However, for the whole earth's magnetic field, this effect is still very small. In addition, the temperature drop caused by solar eclipse will not be great. The process of total solar eclipse can be divided into the following five periods: initial loss, eclipse, eclipse, luminescence and last contact.
