China News Agency, Nanjing, July 1 (Reporter Yang Yanci) A reporter from China News Agency learned from the Purple Mountain Observatory of the Chinese Academy of Sciences on July 1 that there is an appointment for the best film in the Tianxiang Theater in July: "The Smallest Sun" and "The Largest Full Moon" one after another. Come; the occultation of Mars and Venus with the moon bring Tianyu "intimate moments"; a mysterious and small meteor shower continues the romance at the end of the month.

  On July 4, a sun that is much smaller than usual will become the focus of Tianyu.

At 15:11 Beijing time on the same day, the earth will pass the aphelion, which is the moment when the earth is the farthest from the sun in a year.

Therefore, the apparent diameter of the sun is the smallest in the whole year, which is the rare "smallest sun".

  The "mini" sun ends, and the "giant" moon debuts.

This month's blockbuster celestial phenomenon - the annual "biggest full moon" will appear in Tianyu at 2:38 on the 14th, Beijing time.

  Experts suggest that since the "biggest moment" of the full moon will appear at night, interested members of the public may wish to witness and photograph the beauty of "a round of bright moon sky photos" on the evening of the 13th.

  This month's planetary show is also a good show, with Mars and Venus appearing one after another, and "hand in hand" with Moon Girl to bring wonderful performances.

  From the late night of the 21st to the early morning of the 22nd, the moon covered Mars quietly appeared.

The best observation site for this lunar occultation of Mars is in the far northeast of Asia.

In China, Heilongjiang and Jilin in the northeast can also see the "occultation of stars".

Observers in other parts of China can see Mars and the moon "cuddling up".

At that time, two bright celestial bodies, one red and one yellow, are less than 1° apart, which is very worth seeing.

  After "passing" with Mars, the moon came to the vicinity of Venus on the 27th, and the shining Venus accompanied the moon to decorate the night sky.

According to experts, during this Venus conjunction, the bright Venus will rise with an extremely thin waning moon, about 3.5° apart.

As long as the sky is clear, the public can freeze this beautiful fairy tale with the naked eye.

  In the summer night sky in the northern hemisphere, meteor showers are occasionally late but not absent.

  On July 30, the delta Aquarius southern meteor shower ushered in a great, and its ZHR (maximum zenith flow per hour) can reach 25.

Typically, the shower's active period lasts from July 12 to August 23.

  Although the flow is not large, there is no moonlight interference before and after the maximum period of this romantic meteor shower. The radiant point rises after dark and can be seen almost all night. The observation conditions are relatively good, and meteor shower enthusiasts can look forward to it.
