DETERMINING THE CULMINATION OF A CELESTIAL BODY

Abstract

The meridian passage time does not always coincide with the culmination time of the celestial body. The difference is in the local hour angle. At the culminate the celestial body is crossing the observer’s celestial meridian and is said to be in the upper transit. Often, culmination is used to mean upper culmination. A few celestial body altitudes measured around local apparent noon can give a more accurate position fix than using single measurement. In the following article the problem solving equation based on the interpolation polynomial in the Lagrange’s form will be shown. This method can easily be solved using a programmable hand-held calculator.
