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.
If a star's azimuth is 90 degrees, it is located directly east on the horizon. An altitude of 45 degrees means that the star is positioned halfway up in the sky, forming a right angle with the horizon. Therefore, this star would be visible in the eastern sky at an angle that is halfway between the horizon and the zenith.
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.
In a general sense, there is one zenith for each observer at a specific location on Earth, defined as the point in the sky directly above them. However, if you consider multiple observers in different locations, there can be countless zeniths, as each person's zenith corresponds to their unique position on the planet. Thus, the number of zeniths is effectively infinite when accounting for all possible observer locations.
If you are at a location with a latitude of 10 degrees north, a star with a declination of 10 degrees would be located directly overhead, at your zenith. This means the star is in the same plane as your latitude, making it the highest point in the sky relative to your position.
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.
For an observer at latitude 35 degrees, the highest the sun can ever be in his sky is roughly 31.5 degrees above the horizon.
To accurately determine the solar zenith angle for a specific location and time using calculations, you can use the formula: Solar Zenith Angle = 90° - (latitude + declination angle + time correction factor) where: Latitude is the geographic coordinate of the location Declination angle is the angle between the rays of the sun and the plane of the Earth's equator Time correction factor adjusts for the time of day and year By plugging in the values for latitude, declination angle, and time correction factor, you can calculate the solar zenith angle for the desired location and time.
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°.
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.
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.
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).
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).
