Notes: a = alpha and b= beta in the designations. alpha, beta, gamma, etc. give the traditional order of brightess of the stars in a constellation. The traditional order is frequently inaccurate. The capital A in the designation indicates, the star being considered is the primary star of a binary or higher order multiple star system. The abbreviations in the designations are for the constellation in which the star is found: e.g., CMa stands for Canis Major. The 88 IAU official constellations are detailed at Munich Astro Archive . The relative visual flux of Sirius is set to 1. The unaided eye actually responds very roughly like the logarithm of flux. For this reason magnitudes are often presented rather than flux or relative flux. See Magnitudes and the Magnitude System. _______________________________________________________________________________We can locate some of the brightest stars on a sky map.
Sirius , Betelgeuse, and Aldebaran are all in the vicinity of Orion.
