To facilitate the public's observation of this solar eclipse, after calculations, Associate Researcher Cao Yun from the Zijin Mountain Astronomical Observatory of the Chinese Academy of Sciences obtained the time when the solar eclipse would be visible in China's main cities. Cao Yun introduced that a total solar eclipse mainly includes several key time nodes: first contact, the moment when the apparent disk of the moon approaches and makes external tangency with the apparent disk of the sun, which marks the beginning of the eclipse; maximum eclipse, the moment when the centers of the moon and sun are closest to each other. At this point, the largest part of the sun appears covered. During a total solar eclipse, maximum eclipse is also the time when the sun is completely obscured; last contact, the moment when the apparent disk of the moon makes external tangency again with the apparent disk of the sun, marking the end of the eclipse for that location.
