Step 1: Determine latitude and longitude Determine the latitude and longitude of the starting point, or observation point, from which you'll calculate the angle. Use L to represent the starting point latitude. Tip Find latitude and longitude by going to the location with a GPS device. Step 2: Find object's coordinates Find the latitude and longitude of the celestial object. Use D to represent the latitude of the point on the earth where the desired object is straight overhead. Step 3: Find t Find the meridian angle, represented by t, also known as the local hour angle -- or LHA. It is the difference between the observer's longitude and the longitude of the celestial object. Step 4: Calculate the altitude Calculate the altitude of the object, called H. Multiply the sine of L by the sine of D. Then multiply the cosine of L by the cosine of D, by the cosine of t. Add these two products and determine the arcsine of the sum. Step 5: Compute azimuth Find the azimuth angle, Z, by multiplying the cosine of D by the sine of t, and dividing the product by the cosine of H. Then determine the arcsine of the result, which will give you the azimuth angle. Did You Know? The distance between Earth and our moon is, on average, 238,900 miles.
