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.

http://www.space.fm/astronomy/starsgalaxies/equatorialcoordinates.html WebRight Ascension is measured in hours (h), minutes (m) and seconds (s) and is abbreviated as RA or α. If a star lies on a line between where the Sun crosses the Celestial Equator in spring and north (or south) then it will be said to lie at 0h 0s 0m° RA. If it lies 90° to the east* it would be located at 6h RA (360/90 = 4. 24/4 = 6). RA and DEC
