 Bayer designation - Wikipedia, the free encyclopedia
These designations, which were introduced by Johann Bayer in his star atlas Uranometria (named after Urania) in 1603, consist of a Greek letter followed by the genitive (in Latin) of the name of the constellation in which the star lies.
And there are even cases where a star has a designation for a constellation in which it does not lie (according to the modern constellation boundaries).
Note that uppercase Latin Bayer designations never went beyond Q, and names such as R Leporis and W Ursae Majoris are variable star designations, not Bayer designations.

 Bayer designation
These designations, which were introduced by Johann Bayer in his star atlas Uranometria in 1603, consist of a Greek letter followed by the genitive of the name of the constellation in which the star lies.
In practice, there are numerous examples where the designations are out of order, and there are even cases where a star has a designation for a constellation in which it does not lie (according to the modern constellation boundaries).
Note that uppercase Latin Bayer designations never went beyond Q, and names such as W Virginis are variable designations, not Bayer designations.

Johann Bayer introduced a system of designating the brightest stars in each constellation by means of Greek (or less often) Latin letters, a system which is still widely used.
John Flamsteed's numbering of stars within constellations have also remained popular, although Bayer's Greek letters are usually preferred when there is a choice.
In the absence of any better means of designating a star, catalogue numbers are generally used.

Eight Bayer subsidiaries around the world are dropping the country designation from their name; Bayer UK Ltd, for example, has become Bayer plc.
These designations, which were introduced by Johann Bayer in his star atlas Uranometria (named after Urania) in 1603, consist of a Greek letter followed by the genitive of the name of the constellation in which the star lies.
Although most common Bayer letters are Greek, it should also be mentioned that the system was extended, first by using lowercase Latin letters, and then by using uppercase Latin letters.

 Bayer-Flamsteed Designations
This is a shorthand notation for the Bayer-Flamsteed designations of the stars.
The first number, if present, is the Flamsteed designation for a given star, which numbers the brighter, visible stars in a constellation in a sequence from west to east by right ascension.
Bayer ranked the stars (not always precisely) by brightness, with the alpha star typically being the brightest in a given constellation, beta the second brightest, and so on, down through the Greek alphabet.

This star is a double star, with components of magnitudes 4.0 and 7.4.
The second brightest is CS Camelopardalis (which has neither a Bayer nor Flamsteed designation).
The following table lists all stars in Camelopardalis with a Bayer or Flamsteed designation, as well as all stars brighter than magnitude 4.50.

 Star Names
The first designation, using the Greek letter alpha, is called the Bayer designation and represents its primary placement (not always its brightness) in the constellation of Canis Major.
The second designation, with the number 9, is called the Flamsteed designation, after the English astronomer whose star catalogue gave rise to the stellar numbering.
Many stars have Bayer or Flamsteed designations, although in the larger scheme of things, even those stars are considered amongst the brightest the night sky has to offer.

Another plan, introduced by John Flamsteed in 1725 (Flamsteed's British Catalogue) numbered the stars visible to the naked eye consecutively from west to east across the constellation.
The convention used in designating stars by any of the various systematic methods is to denote any lettered or numbered star in a constellation by the letter or number followed by the genitive case of the Latin name of the constellation.
For example, a Canis Majoris (Sirius is its personal name) is the Bayer designation of the brightest star in Canis Major, and 61 Cygni is the Flamsteed designation of the star in the Flamsteed catalogue which is numbered 61 from the western boundary of Cygnus.

In my experience, the most common designation for active regions is the one assigned by the National Oceanic and Atmospheric Administration (NOAA, see http://www.sec.noaa.gov/today.html).
Other designations that are sometimes used are the Mount Wilson designation (assigned by Mount Wilson Observatory, see http://www.astro.ucla.edu/~obs/150_srep.htm) which is currently at about 28600 and apparently started in 1917, and the Big Bear Solar Observatory designation (http://www.bbso.njit.edu">) which started around 1981 and is currently at about 4000.
The advantage of the NOAA designation is that it seems to be the most commonly used one today.

Note that there are companies that purport to name obscure stars after paying customers, but these names are recognized by nobody except the registering company and the customer, and there is nothing to stop two companies from claiming the same star, or even one company from registering the same star to two customers.
Most of these derive from Arabic, but there are also a few Latin ones, such as Polaris, and even a few English ones, such as Barnard's Star.

 Naming Stars
Another popular naming scheme is the use of the so-called Flamsteed numbers, which were introduced in the catalog Historia Coelestis Britannica which had been compiled by John Flamsteed (1646-1719), and was published unauthorised in 1712 after editing by Edmond Halley (1656-1742); Flamsteed's own corrected publication of this work did not contain the numbers, btw.
Eventually, variables are named as follows: The designation of variables consists of one or two letters and constellation name (such as U Sagittarii or RR Lyrae) or a number preceded by "V" and the constellation name (e.g., V 1500 Cygni).
Counting, this scheme provides 334 designations for each constellations, and variables starting from number 335 are designated "V 335", "V 336" etc. Those already assigned a Bayer designation are not given a new name according to this scheme (such as Delta Cephei, Beta Lyrae, Beta Persei [Algol], or Omicron Ceti [Mira]).

Following up on Bayer was John Flamsteed introduced another system in Historia coelestis Britannica who kept the genitive-of-the-constellation rule for the back end of his catalog names, but used numbers instead of the Greek alphabet for the front half.
The catalogue was compiled by Annie Cannon and her co-workers at Harvard College Observatory under the supervision of Edward Pickering, and was named in honour of Henry Draper, whose widow donated the money required to finance it.
Star names from these catalogues include the initials of which of the four catalogues they are from (though the Southern follows the example of the Bonner and uses BD), followed by the angle of declination of the star, followed by an arbitrary number as there are always thousands of stars at each angle.

This is a combination of the two designations.
The Flamsteed number, if present, is given first; then a three-letter abbreviation for the Bayer Greek letter; the Bayer superscript number, if present; and finally, the three-letter constellation abbreviation.
Most of the additions are designations from catalogs mostly now forgotten (e.g., Lalande, Groombridge, and Gould ["G."]) except for certain nearby stars which are still best known by these designations.
