Solving GHA Of Aries

Find the GHA of Aries from the following: GHA of star 061° 34. 5' and SHA of star 301° 47.6'? 

Given:

           GHA of star = 061° 34.5'

            SHA of star = 301° 47.6'

What is asked?

           Find the GHA of Aries 

Solution:

1. We have to subtract the GHA of star and SHA of the star to get the value of the GHA of Aries. 

     GHA of Aries = GHA of star - SHA of star

     GHA of Aries = 061° 34.5' - 301° 47.6'

2. Since GHA of star is less than the SHA of star, we have to add 360° to the GHA of star.

                  GHA of star =   061° 34.5'

                                           + 360°           

                  GHA of star =   421° 34.5'

3. Then minus     SHA =   301° 47.6'     

4. So the GHA of Aries =  119° 46.9'
