How is right ascension measured

WebHow do you calculate the right ascension? Convert the right ascension into decimal form using the following formula: hour + minute/60 + second/3600 = decimal value. For example, if the right ascension is 2 hours, 30 minutes and 45 seconds, then this time in decimal form is 2 + 30/60 + 45/3600 = 2.5125. Multiply the decimal time by 15 degrees. WebThe Right Ascension of the Ascending Node (a W) indicates the geocentric Right Ascension (R.A. or a) of a satellite as it intersects the Earth's equatorial plane traveling northward (ascending). Its value can range anywhere from 0 to 360 degrees.
