Imagine the Earth was a transparent sphere (actually the shape is slightly oval; because of the Earth's rotation, its equator bulges out a little).

Observing from Northern Latitudes
We're pleased that Lydia has had the opportunity to interview Timo-Pekka Metsälä, a Finnish amateur astronomer.
latitude (geographical, of a place): [φ, PHI, Lat] Note: avoid LAT, since it can be confused with local apparent time. It is the angular position of a place north or south of the equator.

FIND LATITUDE / LONGITUDE OF A SPOT ON CCD IMAGE
We can find the latitude ( q ) and longitude ( f ) of a particular feature on Mars’ globe using simple trigonometry.
[edit] Latitude
Latitude was measured in the past either at noon (the "noon sight") or from Polaris, the north star. Polaris always stays within 1 degree of celestial north pole.
Is your latitude in the range listed? You can look up the latitude of various cities at MIT's Geography Page.
What time are you looking? For every hour after 9:00 PM, the best date to see a constellation moves ahead half a month.
Latitude can also be determined by the direction in which the stars travel over time. If the stars rise out of the east and travel straight up you are at the equator, but if they drift south you are to the north of the equator.
Latitude-time plots of jet streams under the Sun's surface show the surprising shutdown of the solar cycle mechanism.

At latitudes closer to the Poles than 45 degrees latitude, the Sun's sunrise and sunset points change by more than one half degree daily. For example, at Barrow, Alaska, which resides at 71 degrees north latitude, the sun rises and sets a whopping 1.

The latitudes at which sunspots appear vary as the sunspot cycle progresses. Individual sunspots do not move up or down in latitude, but new spots appear closer to the equator as older ones at higher latitudes fade away. Figure 16.

ecliptic latitude & longitude:
System of coordinates that define the position of an object in the sky.
Visto desde latitudes medias del hemisferio norte (alrededor 40 grados), Centauro nunca está en el cielo. A medida que se va hacia el sur de la Tierra, por debajo del ecuador, definitivamente puede verse de cuando en cuando.
The highest latitude at which martian gullies have been found is around 70°-75°S on the walls of pits developed in the south polar pitted plains. If you were at this same latitude on Earth, you would be in Antarctica.
What is the latitude of the Observatory?
Meridian line laser and Flamsteed house, Old Royal observatory from the grounds of the National Maritime Museum.
Airy's Transit Circle lies at Longitude 0°, by definition, and Latitude 51° 28' 38'' N.
Well, if your latitude is 35oN any star with a declination of more than +55o will be a circumpolar star.
Visible between latitudes 90 and -30 degrees

In the southern latitudes, Orion appears differently in the sky. In Australia and New Zealand, his belt and sword are known as the Pot or Saucepan.

Visible only from latitudes south of about 25 degrees N, the star we call Alpha Centauri lies 4.35 light-years from the Sun. But it is actually a triple star system. The two brightest components Alpha Centauri A and B form a binary.

A faint visual phenomenon associated with geomagnetic activity, which occurs mainly in the high-latitude night sky; typical auroras are 100 to 250 km above the ground. AURORAL OVAL.
Auroras are most often observed at high latitudes and are enhanced during geomagnetic storms. Black Hole A region of space that has so much mass concentrated in it that there is no way for a nearby object to escape its gravitational pull.
The Greek name means "before the dog," as in northern latitudes the star rises before Sirius, the "Dog Star," and its constellation Canis Major, announcing their quick arrival.
Sunspots appear usually only between latitudes from 5° to 35° north and south of the sun's equator. Sunspots are not permanent since the sun's surface is gaseous.
The bright collar at âˆ'45° latitude is also connected with methane clouds. Other changes in the southern polar region can be explained by changes in the lower cloud layers.
Surface temperatures depend on latitude and fluctuate over a wide range from day to night. At the Viking 1 lander site, the temperature regularly varied from a low near 189 K, just before sunrise, to a high of 240 K in the early afternoon.
It has a known fixed position, at latitude 90° North. The boundaries of Canada extend all the way to the Geographic North Pole. There is no land at this location, which is usually covered by sea ice.
A second jet stream is located at the poleward limit of the equatorial tropical air above the transition zone between tropical and mid-latitude air. This subtropical jet stream is usually found at latitudes 30 to 40in general westerly flow.
Evidence of subsurface ice prevails, especially in the form of petal-shaped ejecta blankets around some craters, vast areas of collapsed chaotic terrain, and so-called patterned ground at high northern latitudes.
The celestial equivalent of latitude is called declination and is measured in degrees North (positive numbers) or South (negative numbers) of the Celestial Equator. The celestial equivalent of longitude is called right ascension.

Generally located between latitudes of 60-70 degrees north and south of the equator - because the interaction of magnetic fields and charged particles is greatest near the Earth's magnetic poles - and at an altitude of 100 to several hundred ...
Declination is very much like latitude on the Earth. A Dec of 0 degreed points to the "Celestial Equator" just like a latitude of 0 is at the Equator.
Jupiter and the other gas planets have high velocity winds which are confined in wide bands of latitude. The winds blow in opposite directions in adjacent bands.
The radiant, which is only a few degrees from Procyon, is sufficiently high for observation by about an hour after local midnight at the latitude of New Zealand.
If you reside at 25 degrees north latitude or farther south, look below Jupiter to catch this southern signpost on or near your southern horizon.
In the ecliptic system, latitude is measured with respect to the ecliptic plane and position is measured by ecliptic latitude (elat) and ecliptic longitude (elon). Both ecliptic latitude and longitude are measured in degrees.
