Would appreciate it if you could advise if it appears that I have understood correctly..........
GHA
Nautical Almanac
Select date & hour
Increments and corrections tables
Increments are minutes and seconds additional to hour and are always added
"v" corrections are applied when the passage of the HB across the sky is not constant throughout the hour in which the increments are applied.
"v" corrections are added EXCEPT for VENUS when they can be + or -
No "v" corrections for Sun or Aries
Declination
Nautical Almanac
Daily pages
Date & hour
Increments and corrections
No increments
The "d" correction is the only correction required
"d" corrections are 50/50 + or -
Inspect the declination column to determine whether declination is increasing or decreasing and apply "d" correction accordingly
"d" corrections are given for 3 days for Sun and Planets and are correct for the middle day
"d" corrections for Moon are given hourly
Thanks
Mike
