Hi All, Dec 27, 2014
As an exercise in reasoning I attempted to calculate winter minimum
altitude of the sun at solar noon for two locations Kings County (Lat of
44o44' given) and Halifax (Lat of 44o39' given).
With the earth sliced in two along the meridian, minimum altitude (Min),
if my reasoning is correct, should be equal to
Min = 90 -(Lat+23o26')
But for Kings Co. I get Min = 21.83o lower than given of 21.9o by 0.07o
and for
Halifax I get Min = 21.92o lower than given of 22.0o by 0.08o.
Is this discrepancy due the the earth not being quite spherical or
something else ?
Yt, Dw, Kentville
