It swings in the southern sky lower in the winter and higher in the summer. And in the summer it rises and sets further towards the pole and in winter more towards the equator. Would anyone really believe that the path of the sun is so difficult to understand as it relates to the yard and house ? Apparently you are having trouble with it so I think it was worth the mention. Could anyone really believe that they had raised a significant debate point ? Only if you want to take the seasonal position of the sun into account when doing your passive solar design for your house. What is your latitude? What do you think is the difference there between the rising position of the sun between mid winter and mid summer? David |

David It looks like there isn't going to be a continuation from Spy but some may be interested in some facts anyway. These figures are the difference in degrees in the rising position of the sun between 20th June and 20th December. The difference in setting position would be similar. Miami 52 London 79 Moscow 90 Obviously it varies with latitude and the same sort of differences arrise in the southern hemisphere as in the north. There is considerable difference in how the sun strikes your house between summer and winter unless you live in rather low latitudes, basically in the tropics. This is worth considering when designing the passive solar heating/cooling of your house. David |
