Tilt of earth: noon shadows
editNorth of the equator, the sun will appear in the south at noon, so a vertical stick's shadow will point north at noon. The shadow at any one place in the northern hemisphere will be shortest at the summer solstice, June 21, when the noon sun is higher in the sky than any other time during the year. The equator is the only place where the sun is directly overhead, and that happens only on certain days of the year. Therefore the vertical stick will always cast a shadow north of the equator, even at an equinox.

This is my first post; help and suggestions welcomed. Thanks.
rambling and not on subject
editThis article needs complete structural revision. There is an absurd amount of repetition and clutter about passive solar building design which already has its own separate page. https://en.wikipedia.org/wiki/Passive_solar_building_design This page barely touches on the sun's apparent path other than stating the altitude at noon and azimuth at sunrise and sunset, and to generically say it follows an arc without properly defining the shape of the arc from the observers position. The information is also fixed to the specific current tilt of earth's axis to the ecliptic and makes no mention of atmospheric refraction. (there is no reason to restrict the discussion of the sun's path to earth let alone it's specific current tilt) 73.193.32.170 (talk) 15:53, 30 May 2020 (UTC)
