Lupus (abbr. Lup, gen. Lupi)
The Wolf. Lupus is a southern constellation that lies between Scorpius to the east, Centaurus to the west and north, and Circinus to the south. One of its few deep-sky objects of interest to the amateur observer is the open cluster NGC 5822 (visual magnitude 7; apparent diameter 40'; R.A. 15h 05.2m, Dec. -54° 21'). The so-called Lupus Loop is a prehistoric supernova remnant, about 1,500 light-years away (R.A. 15h 10m, Dec. -40°), in the form of a large broken shell, 4.5° in diameter, that is detectable at radio and X-ray wavelengths. See below for details of the constellation's brightest stars.
