China News Service, Nanjing, August 4 (Yang Yanci) The Purple Mountain Observatory of the Chinese Academy of Sciences released August Tianyu’s "Performance Table" on the 4th: This month's astronomical phenomena are dominated by the dynamics of the big planets, and the planets with the moon will frequently appear on the scene. In addition, one of the three major meteor showers in the northern hemisphere-the Perseid meteor shower will be "energetic".

  According to the astronomical forecast, there will be 6 planetary moon astronomical phenomena this month. Although the large planets are "active", not many are suitable for viewing.

  Among them, when Jupiter with the moon and Saturn with the moon occur, the moon phase is close to the full moon, and the viewing effect will be affected. In addition, the conjunction of Mars on the 9th will not appear until close to midnight.

  Relatively speaking, the most suitable for viewing is the dazzling Venus. On August 13th, Venus Xidayuan appeared in Tianyu. By then, "Venus" Venus will slowly rise as the "Venus", and the public can wait for the shadow of Venus in the north-east direction in the early morning.

  After the great distance of Venus, there will be a Venus conjoined moon on the 15th. The phase of the moon on that day is close to the waning moon. If the air quality is good, you can take pictures of the moon, Venus, Milky Way, and Orion.

  The most anticipated celestial phenomenon of this month-the Perseid meteor shower will usher in a great deal from 21 o'clock on the 12th to 0 o'clock on the 13th. The ZHR (zenith rate per hour) of this meteor shower is about 80-120, which not only has a large flow, but also the meteors are fast and bright.

  According to the statistics of the International Meteor Organization, the extreme flows of the Perseids in the past 5 years were 94, 178, 67, 82, and 71. Therefore, the flow of Perseus is still large and stable. As long as the weather, moon phase, and light pollution permit, it is very suitable for astronomers to watch.

  Astronomers suggest that it is not difficult for the public to observe meteor showers, and no special equipment is required. Just choose an open and safe place away from the city lights, find the direction of the meteor shower radiant point, and watch the sky quietly. (Finish)
