text: 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.  \n\nFirst you have to know the latitude of each of these places to find out the position of the celestial equator in the sky.  \n\nLatitudes\nEquator = 0 degrees\nTropic of Cancer = 23.5 N\nTropic of Capricorn = 23.5 S \nDana Point, CA = about 34 N\n\nSo the altitudes of the celestial equator at these positions is 90 minus latitude.\n\nAltitude of celestial equators\nEquator = 90 degrees\nTropic of Cancer = 66.5 from south horizon\nTropic of Capricorn = 66.5 from north horizon \nDana Point, CA = about 56 degrees from south horizon\n\nOn 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.\n\nOn 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:\n\nAltitude of noon Sun on the first day of \nSpring = 56 degress from south horizon\nSummer = 79.5 (56+23.5) degress from south horizon\nAutumn = 56 degress from south horizon\nWinter = 32.5 (56-23.5) degress from south horizon\n\nHope that was clear
