text: altitude of noon sun during the four different seasons of the year? in equator? tropic of cancer? tropic of capricorn? dana point? the position of the noon sun varies throughout the year.  during the summer months it can be located as much as 23.5 degrees above (or north of ) the celestial equator and in winter the same angle below (or south of) the celestial equator.    first you have to know the latitude of each of these places to find out the position of the celestial equator in the sky.    latitudes equator = 0 degrees tropic of cancer = 23.5 n tropic of capricorn = 23.5 s  dana point, ca = about 34 n  so the altitudes of the celestial equator at these positions is 90 minus latitude.  altitude of celestial equators equator = 90 degrees tropic of cancer = 66.5 from south horizon tropic of capricorn = 66.5 from north horizon  dana point, ca = about 56 degrees from south horizon  on the vernal and autumnal equinoxes the position of the noon sun is on the celestial equator.  so just look at the above list to read off the altitude.  on the summer (winter) solstice the position of the noon sun is 23.5 north (south) of the celstial equator.  so just add or subtract 23.5 degrees from the list above of altitudes.  for example dana point:  altitude of noon sun on the first day of  spring = 56 degress from south horizon summer = 79.5 (56+23.5) degress from south horizon autumn = 56 degress from south horizon winter = 32.5 (56-23.5) degress from south horizon  hope that was clear
