Gary,
What do you think of figuring the Sun's GHA "v" for the first of each month then jotting the result down at the bottom of the page for the entire month ?
For those with a scientific calculator the increment table and "v" can be bypassed. Just multiply the hourly GHA(DD.dd) difference by minutes(MM.mm)/60 then convert back to GHA degrees(DD.MM.mm) to add to hourly NA figure.
