South celestial pole

Astronomy South Atlantic AnomalySouthern Lights

Its only notable feature is the South Celestial Pole, with is marked (within a degree or so) by the faint star σ Octantis, and is identified above.

 


IRAS Mosaic of the South Celestial Pole
The infrared sky at the south celestial polar cap is displayed in this image constructed from nine fields of the Infrared Astronomical Satellite (IRAS) Sky Survey Atlas.

south celestial pole Point on the celestial sphere directly above the Earth's south pole.
spectral class Classification scheme, based on the strength of stellar spectral lines, which is an indication of the temperature of a star.

south celestial pole: The point of the celestial sphere directly above Earth's South Pole.
south point: The point on the horizon directly above the south celestial pole; exactly south.

South Celestial Pole - The point above the Earth's South Pole where the Earth's polar axis, if extended outward into space, would intersect the celestial sphere.

South Celestial Pole (SCP)
A direction determined by the projection of the Earth's South Pole onto the celestial sphere. The SCP is exactly 180 degrees from the North Celestial Pole and corresponds to a declination of -90 degrees.

To find the south celestial pole in the sky at this moment, one is less lucky, as that area is a particularly bland portion of the sky, and the nominal south pole star is Sigma Octantis, which with magnitude 5.

North and South Celestial Poles

south celestial pole (SCP): projection of the Earth's south pole onto the sky. The SCP altitude = the observer's southern latitude. spacetime the four-dimensional combination of space (three dimensions) and time (the fourth dimension).

Follow The Southern Cross Constellation
Crux, also known as the Southern Cross Constellation, is the smallest of the 88 constellations.

celestial pole Either of the two points of intersection of the celestial sphere and the extended axis of the earth, labeled N or S to indicate whether the north celestial pole or the south celestial pole.

One of the closest constellations to the South Celestial Pole (which is held by its neighbor, Octans), Apus (the Bird of Paradise) is also one of the smaller and more obscure.

Over the years, astronomers have added constellations to fill in the gaps between Ptolemy's figures and map the uncharted regions of the sky near the south celestial pole.

In the celestial coordinate system the North and South Celestial Poles are determined by projecting the rotation axis of the Earth to intersect the celestial sphere, which in turn defines a Celestial Equator.

This point is the South Celestial Pole.
Method two: Canopus and Achernar
The second method uses Canopus (the second brightest star in the sky) and Achernar. Make a large equilateral triangle using these stars for two of the corners.

Plancius instructed Keyser to make observations to fill in the constellation-free zone around the south celestial pole.

One axis is pointed at the North or South Celestial Pole, depending on the latitude of the observer, and permits east-to-west travel. This axis is called the Polar or Right Ascension Axis.

(See More Precisely 1-1 for a discussion of angular measure.) Thus, the celestial equator is at a declination of 0°, the north celestial pole is at +90°, and the south celestial pole is at -90° (the minus sign here just means "south of the celestial ...

If you want to put in the South Celestial pole and those angles you can, but here you don't need them. Let's put the object in the picture. What was its location? In case you forgot, it is 30º above the northern horizon.

The projection onto the sky of the Earth's axis of rotation results in two notable points at opposite directions: the north and south celestial poles. Because of precession, these points trace out circles on the sky.

Similarly, a Dec of +90 degrees points to the "North Celestial Pole" and -90 degrees points to the "South Celestial Pole." The word Celestial is used to distinguish between, for example, the North Pole in the sky and the North Pole on the Earth.

The upper meridian passing through the north and south celestial poles, and the observer's zenith. This view is looking from the south towards the north for an observer in the Northern Hemisphere.

When using a telescope with an equatorial mount, one aligns the polar axis of the mount with the north or south celestial pole.

Created between 1750-1754 by French astronomer Nicolas Louis de La Caille from stars found near the south celestial pole. The constellation was originally called Mons Mensae.

People in the northern hemisphere can never see stars near the south celestial pole, and people on the southern hemisphere can never see Polaris. Poor southerners, there is no bright star near the south celestial pole.

The most interesting star in the constellation is the faint white giant sigma Octantis, a Delta Scuti type variable star and the nearest star to the South Celestial Pole visible to the naked eye.

Celestial pole
the north and south celestial poles are points on the celestial sphere where earths axis of rotation intersects the celestial sphere.

The Bird of Paradise, originally called Avis Indica; a small, faint constellation lying near the south celestial pole, immediately south of Triangulum Australe (the Southern Triangle). See below for details of its brightest stars.

R.A. is one of the co-ordinates used to locate positions on the celestial sphere. Lines run from the North to the South celestial pole and are similar to the Earth's lines of longitude, except that they are measured in units of time.

The effects of precession will take Canopus within 10° of the south celestial pole around the year 14,000 AD.[7] ...

South: one of the cardinal points of the compass, it is the direction opposite north, in the direction of the south celestial pole. It is also the direction of the sun at local noon (in the northern hemisphere).

Polaris Australis (Sigma Oct)
Octans was named by Abbé Nicolas Louis de Lacaille. Octans is the constellation which contains the South Celestial Pole. Unlike Ursa Minor's Polaris, there is no bright star near the South Pole.

The celestial equator is defined as being at declination zero (0) degrees; the north and south celestial poles are defined as being at +90 and -90 degrees, respectively.

If the earth's axis is extended, the points where it intersects the celestial sphere are called the celestial poles; the north celestial pole is directly above the earth's North Pole, and the south celestial pole directly above the earth's South ...

Celestial poles Points on the celestial sphere directly above the Earth's poles about which all the stars seem to rotate; known as the north and south celestial poles (NCP and SCP).

c. Imagine the earth's north and south pole projected out onto the sphere. These would be called the north celestial pole and the south celestial pole respectively.

Orion, near the June solstice point at the border of the constellations Taurus and Gemini -- shown on this star chart, where the ecliptic intersects the 6-hour meridian extending from the north celestial pole to the south celestial pole.

declination: A method of establishing a celestial object's location by using the angular distance north or south of the celestial equator. Similar to a latitude designation on the planet Earth. It is measured from -90o at the south celestial pole ...

Polar Alignment - Making the polar axis of an equatorial mount parallel to the Earth's axis of rotation by pointing it accurately at the North Celestial Pole in the Northern Hemisphere, or the South Celestial Pole in the Southern Hemisphere.

Only a planet in an almost polar orbit and situated near the south celestial pole could have escaped his detection. He could have picked up a Neptune-sized planet at seven times the distance of Pluto, or a Pluto-sized planet out to 60 AU.

Continuing his journey towards the south, the north celestial pole sinks below the horizon; the south celestial pole rises above it; or to speak more exactly, the zenith of the observer approaches that pole.
