The Perpetual Almanac does not compute the semi-diameter of the moon, but there is a statment in the Help file that describes "SD" as the value of the semi-diameter for sun or moon, so that is misleading. we apologize.

If you need the value of the SD of the moon for past years it can be found at the USNO Astronomical Applications website, under Celestial Navigation Data. Just enter time and date. If moon is not there, change the time some till it shows up.
