Leo (the Lion), with Jupiter Almost in His Mouth, Is Conspicuous in March UST BELOW the zenith, Leo is easily identi fied by a sickle-shaped formation of stars with the bright star Regulus at the end of the "handle" (page 114). Below Leo, Hydra, the Sea Ser pent, sprawls across the whole center of the southern sky (page 115). A curious pentagon of stars forms its head, and the lonely bright star Alphard is its heart. West of Leo lies Cancer (the Crab), a zodiacal constellation, its faint stars forming a rough Y outline. In the northern sky, Ursa Major (the Great Bear), with the Big Dipper inverted, lies clumsily on its back and stretches its paws to the zenith. Saturn and Mars now have moved far to the west, Mars having passed Saturn early in the month. Jupiter, south of the zenith, is the most striking object in the sky. Antlia (the Air Pump) is located below the central part of Hydra. It is one of many minor southern constellations named in 1752 by La caille, a French astronomer, for his laboratory instruments, merely to fill empty space in this region of the sky (page 115). The sky chart for March also is correct for early-morning use on December 1 at 5:30 a.m .; December 15, 4:30 a.m .; January 1, 3:30 a.m .; January 15, 2:30 a.m.
