Nautical Almanac 1992 Increments | And Corrections Pdf

This matches the 1992 printed increment for Sun. If you meant something else by — such as hidden table logic, computational shortcuts for 1992 calculators, or how to correct for Moon’s HP (horizontal parallax) — let me know and I’ll go even deeper.

Example: 25m 30s → (15 \times 0.425 \times 60 = 382.5′ = 6° 22.5′) Nautical Almanac 1992 Increments And Corrections Pdf

[ \textIncrement (GHA) = t \times 15^\circ + \textcorrection for v ] This matches the 1992 printed increment for Sun

But the printed table pre-computes:
