Semi-diameter of moon
From: Bob Goethe
Date: 2018 Jan 20, 12:25 -0800

The semi-diameter of the moon changes enough that it appears to have a different value every day, from the bottom of the "Moon" column in the Nautical Almanac. I just today realized that I have never knowingly made a correction for S.D. for the moon.

Would I be correct in assuming that the horizontal parallax value incorporates a correction for semi-diameter?

Thanks,

Bob
