RE: Using HP-65 Sunrise/Sunset
In a nutshell, yes. Pick your convention and tailor the formula to reflect that.

I use the HP formula therefore N and W are +ve; S and E are -ve.

Coincidentally my photometrics, mapping and surveys and all my navigation courses have been based on the above convention as are my HP manuals.

Cheers, Geoff
