		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.
		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.
		Variable stars are named using a variation on the Bayer designation format of an identifying label (as described below) combined with the Latin genitive of the name of the constellation in which the star lies.

	Variable star designation - Wikipedia, the free encyclopedia
		Variable stars are named using a variation on the Bayer designation format of an identifying label (as described below) combined with the Latin genitive of the name of the constellation in which the star lies.
		Sample designations are R Coronae Borealis, YZ Ceti, and V603 Aquilae.
		In previous centuries few variable stars were known, so it seemed reasonable to use the letters of the Roman alphabet, starting from the letter R so as to avoid confusion with letter spectral types or the (now rarely used) Latin-letter Bayer designations.

	Wolf 1055 AB / Van Biesbroeck's Star
		Both Stars A and B are flare stars, but the fainter member of the system was once thought to be low enough in mass to be a possible brown dwarf and is now commonly referred to as "Van Biesbroeck's Star" (or VB 10) after its discovery in 1940 by George Van Biesbroeck (1880-1974).
		Star A's high proper motion was later rediscovered by by Frank Elmore Ross (1874-1960), who reported on the star in April of 1927 with his "Fifth List of New Proper-Motion Stars," Astronomical Journal (37:886).
		Although the star's normal surface temperature is 4,500° F, the sudden burst heated VB 10's outer atmosphere to around 270,000° F. The astronomers attributed this rapid heating to the presence of an intense, but unstable, magnetic field (Linsky et al, 1995).

		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.
		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.

	Star designation - Wikipedia, the free encyclopedia
		Because of imprecision in old star catalogs, it may not be clear exactly which star within a constellation a particular name corresponds to (eg, Alniyat, Chara).
		For instance Barnard's star has the highest known proper motion of any star and is thus notable even though it is far too faint to be seen with the naked eye.
		A very few stars are named for individuals; this is rare and many cases were unofficial names that became official.

		When the star is not included in the largest catalogues, we have tried to find an identification in existing catalogues and lists, according to the star specific characteristics (high luminousity, large proper motion, faint and blue, and so on).
		Star are sometimes identified by the constellation name and a sequential number.
		We have therefore designed a specific code number to record them containing the constellation code and a key to the bibliographic reference.

	Supernova 1054 - Creation of the Crab Nebula
		On July 4, 1054 A.D., Chinese astronomers noted a "guest star" in the constellation Taurus; Simon Mitton lists 5 independent preserved Far-East records of this event (one of 75 authentic guest stars - novae and supernovae, excluding comets - systematically recorded by Chinese astronomers between 532 B.C. and 1064 A.D., according to Simon Mitton).
		This star became about 4 times brighter than Venus in its brightest light, or about mag -6, and was visible in daylight for 23 days.
		The Supernova 1054 was later also assigned the variable star designation CM Tauri, a designation which is sometimes also used for the (optical) Crab pulsar.
