Nautical Almanac

Seadogg · 31-01-2007, 07:59

Hey, gang!

I'm working on a project and don't have access to my almanac.

Could someone post the NA's Equation of time for, say, the next few days? I'd really appreciate it. (Or a way to convert the EoT that's on various astronomy sites into something that can be used for Cel Nav calculations!)

Thanks in advance!

Fair Winds,

Nick

Thanks, Gord! I appreciate your input. However, what I'm looking for is the format that this is presented in the Nautical Almanac (e.g. degrees, minutes not minutes and seconds).

OR....if you know how one would quickly convert the minutes-secs into degrees, minutes, that would work too!

Thanks again!

1 degree = 60 minutes = 3600 seconds

Thus

d + (m / 60) + (s / 3600) = decimal degrees

or any other form of playing with it. To get decimal minutes

m + (s / 60) = decimal minutes
