solar altitude angle= (90 degree - zenith angle )
Noon is when the sun is overhead or at its zenith for whichever part of the world you are on. The angle would depend on the time of year and your latitude.
Zero, Zenith, zillion (informal).
If you are asking about time-related A M and P M then it means - Ante meridian and post meridian. "Ante" is Latin for "before", "post" means after.Meridian is when the sun reaches its zenith, the highest point in its daily arc; i.e., noontime.
Nadir comes for the arabic nazir, meaning opposite. Nadir is the direction directly below a point. It is in a way the opposite to Zenith. The word is also used in the meaning of the lowest point.
Scientific or technical words from Arabic include alcohol, alchemy, Aldebaran, alembic, alfalfa, algebra, alkali, Altair, caraway, cipher, nadir, zaffer, zenith, zero, zircon.
Viewed from latitude 55° north, the sun's highest altitude on June 21 is31.5° down from the zenith, or 58.5° up from the horizon.
At the time of the southern hemisphere's winter solstice, the sun is directly over the Tropic of Cancer, which circles Earth at 23.44° north latitude. So at 6° south latitude the sun appears 29.44° from the zenith (a location's zenith is directly overhead). Since there are 90° between the zenith and the horizon, the angle for which you are looking is the difference between 90° and 29.44°, 60.56°.
An object seen halfway between the horizon and the zenith has an altitude of 45 degrees.An object seen due east of the observer has an azimuth of 90 degrees.
Perth is at 32 degrees south and on the summer solstice the Sun's declination is 23½ degrees south. Therefore the Sun is 32-23½ degrees or 8½ degrees from the zenith, that is 81½ degrees above the horizon.
The zenith is the name of the point that is directly over a particular location. Astronomers use this term when referring to the altitude of a celestial object, such as the sun or moon.
An observer at latitude 79°, whether north or south, can never see the sun at his zenith. That's only possible for observers whose latitude is less than 23.5°, either north or south.
That depends on the latitude from which you are observing Polaris.At the Equator (0 latitude) Polaris will be tangential to the northern horizon (0 degrees of altitude)At 52 degrees north the altitude of Polaris will be 52 degreesTherefore At the North Pole (90 latitude) Polaris will be overhead (90 degrees of altitude).
The angle between the celestial equator and your personal zenith is equal to the latitude of your location. (Whether it's north or south latitude doesn't matter, and neither does your longitude or the time of day or night where you are.)
As seen from 25 degrees north latitude and ANY longitude, Polaris (the 'North Star', the 'Pole Star') appearswithin about 1/2 degree of due north and 25 degrees above the northern horizon, at any time.
That depends on your latitude. Also, it does NOT depend on the season. If a star passes near the zenith in Summer, it will also pass near the Zenith in Winter, although it may not be visible in one season or the other (when it passes near the Zenith during the daytime).
30 degrees for observers at a latitude of 30 degrees north
That lies on 23.5 degree latitude, at which the Sun may appear directly overhead at its zenith.
