a.According to the Starry Night program, which constellation the Sun was actually in at the instant of a person birth on August 12, 1953.

b. What was the right ascension of the Sun on the moment a person was born on August 12, 1953.
c. What constellation is this position in?

To find the answers to these questions, you can use the Starry Night program or a similar astronomical software. However, since I am unable to access specific software, I can guide you on how to find the information using alternative methods.

a. To determine the constellation in which the Sun was at the instant of a person's birth on August 12, 1953, you can use online astronomical calculators or ephemeris data. These sources provide the position of celestial bodies, including the Sun, at specific dates and times. Inputting the birth date and time into an online calculator or referring to an ephemeris will allow you to identify the Sun's position at that moment.

b. To determine the right ascension of the Sun at the moment of birth on August 12, 1953, you can use the same online calculators or ephemeris sources. Right ascension is a celestial coordinate determining the east-west direction in the sky, similar to longitude on Earth. By providing the birth date and time, you can acquire the right ascension value for the Sun at that specific moment.

c. Once you have obtained the right ascension of the Sun, you can refer to star charts or astronomical programs like Starry Night to identify which constellation corresponds to that specific position. Constellations divide the sky into regions, and each one contains specific stars, which can be identified by their right ascension and declination coordinates. Cross-referencing the right ascension value of the Sun with star charts or astronomical programs will help you determine the constellation in which the Sun was located at the moment of birth on August 12, 1953.
