    Re: Calculating the time when GHA is equals zero?
    From: Tony Oz

    Dear Steve!

    Thank you for the explanation. I got it like this:

    • there are two given values: the v-corr for the hour in question and the angle left till GHA equals 360°
    • with these values you search through the "INCREMENTS AND CORRECTIONS" table looking for a page where both values could possibly be present in the Moon's column
    • finding them on the 44th minute's page you start searching for the seconds' line where the GHA increment value being added to the v-corr gives the exact value of the angle from the step #1


    Since I disliked that particular brand of NA since I saw it for the first time, I never could make myself to study and master it properly. With your help I seems have overcome this dislike (but I'll still will use the other type of NA).

    Thanks again, warm regards,
    60°N 30°E
