Talk:Declination

From Wikipedia, the free encyclopedia

In the Southern Hemisphere, because our seasons are switched is the formula for the declenation of the sun now:

d = +23.45 * cos(360/365 * (N +10)) ?

Is the Sun Dec now -23°27' at the Southern hemisphere summer solstice and +23°27' at the Southern hemisphere winter solstice?

no, it's just a matter between the sun and the earth, dec is + when the sun is overhead in the northern hemisphere (northern summer, southern winter) and dec is - when the sun is overhead in the southern hemispere (southern summer, northern winter). hope that helps...

Hello, The "more precise formula" requires one to know the fractional year. For this quantity, N is required. Is this really the same as N in the previous paragraph? If so, then this formula appears to be much less accurate then the linked table. Can anybody add a comment on how accurate that formula is? Thank you, Roger Jeurissen.
