Giant cell convection in this body has provided evidence for fast dynamo flow which suggests that this body may have a magnetic field. Its motion shows it to be a member of the OB1 association of its constellation. It was the first star to have its diameter measured accurately by Michelson's interferometer method, and its name is a corruption of the Arabic term for "The Hand of the Central One." Along with Procyon and Sirius, it is the northwestern star of the winter triangle. Its distance was recently revised to 640 light years which makes it the closest red giant to our solar system, and along with Antares, it is one of two supergiants with a magnitude less than one. Misclassified as the alpha star of a certain constellation, for 10 points, name this variable star that, along with Rigel, dominates the constellation Orion.
