The constellation cassiopeia (which looks like a large w) is about the same distance from the north star, but on the opposite side of it from the big dipper.
The earliest known star catalogues are from 1500 bce sumerian and chinese cultures, but they do little more than record the names of stars. It wasn’t until 370 bce, when greek astronomer eudoxus of cnidus wrote his phaenomena, that there was a full catalogue of classical constellations visible from the latitude of the mediterranean.
Astronomical background the key to understanding the properties and evolution of stars is the hertzsprung-russell diagram, first studied around 1910. It plots the luminosity of stars along the ordinate, and the color of stars along the abscissa.

The stars are plotted as gaussian point-spread functions (psf) so the size and amplitude of the stars corresponds to their relative intensity. The stars are also elongated in right ascension (celestial longitude) based on declination (celestial latitude) so stars in the polar regions will still be round when projected on a sphere.

We constructedan il catalogue of 1200 stars: there are 707 stars in the firstpart (with at least 20 years of il observations) and 493 stars inthe second one (less than 20 years).
The right ascensions and declinations of stars are essentially fixed, although they shift very slowly because of precession, a gradual change in the direction of the earth’s axis. 0 is that they show star positions for the beginning of the year 2000.
The two numbers which specify the position of a star, x, in this system are the azimuth, declination is the equivalent of latitude measured in degrees from the it is not possible to use the horizontal coordinate system in a catalo.

This is not just true in high-latitude oceans, fa- mous for cloudy skies; it is a potential problem in all oceans including those of the tropics.
The visible satellite imagery is essentially a snapshot of what the satellite sees, unlike infrared (ir) satellite imagery, which depicts the temperature of the clouds.
Ptolemy next explains how he compiled the catalogue of stars using the spherical astrolabe, an armillary with graduated ecliptic and latitude circles.
Beneath the rete sits a plate inscribed with a projection of sky above an observer at a given latitude: the plate could be removed and replaced with others.
The star is catalogued in the tycho-2 star catalogue as tyc-3521-1800-1. Flamsteed designations such as 23 draconis (23 dra) are named after the creator, sir john flamsteed. Sir john named the stars in the constellation with a number and its latin name, this star's flamsteed.

Altitude observations of the binary system are assumed to be taken at 0o longitude and at all latitudes separated by a tenth of a degree.
In this equatorial system, the analogue of latitude is the declination, the declination of a star is its angular distance in degrees measured from the celestial.
To locate stars in the sky, we use a system of coordinates similar to the one we use to locate places on earth.
On earth maps, we divide the surface of earth into a grid, and each location on that grid can easily be found using its latitude and longitude coordinate.

Brahe pointed out that solar observations ptolemy claimed to have made in 141 are definitely not genuine, and there are strong arguments for doubting that ptolemy independently observed the more than 1,000 stars listed in his star catalog. What is not disputed, however, is the mastery of mathematical analysis that ptolemy exhibited.
In brief, stars detected on the r ccds are matched to catalog stars. The calibration errors in great circle longitude and latitude are given by the attributes.
Imagery products are used to detect weather systems and forecast their movement. The products help identify cloud and atmospheric features during the day and at night. Imagery is composited with multiple sources to support tropical uses, high latitude needs, and day-to-day forecasts.
