These nights, every morning at about 1: 30, in the south, at a height of 45 degrees, what is the name of that bright star and what constellation does it belong to?

It's Jupiter. Jupiter is the brightest star in the whole day this month. I can see it almost all night, and I often watch the stars in the suburbs during this time. It is retrograde in Sagittarius, and Sagittarius is in the southern sky. July this year is the best time to observe Jupiter. On July 9, Jupiter rushed to the sun, and the sun rose from the southeast horizon after sunset, with a brightness of about -2.7, which was visible all night. After the eclipse, Jupiter began to get closer to the sun. At 20 o'clock on June 7, 65438, Jupiter closed the moon, and Jupiter was in the north of the moon.
