Saturn - continues to approach Regulus as it retrogrades to the west. Its disk subtends 20 arc seconds and its rings span 45 arc seconds. At mid-month, the rings are inclined at approximately nine degrees. Since Saturn is now past opposition, the shadow of the planet becomes more prominent on the eastern portion of the far side of the rings. Titan (magnitude 8.4) passes north of Saturn on the nights of March 9 and March 25 and south of it on the nights of March 1 and March 17. During March, Rhea shines at a magnitude of 9.7, Tethys at 10.2, Dione at 10.4, and Enceladus at 11.3. At 11:00 p.m. EDT on the night of March 18, seven of Saturn's moons are visible. Enceladus and Iapetus lie to the west of the ball of the planet and Mimas, Tethys, Rhea, Dione, and Titan will be positioned in increasing distance to the east. Iapetus is just north of Saturn on the night of March 18 and is east or west of the planet by the listed separations at 0:00 UT on the following dates: March 1 (39" west), March 7 (33" west), March 11 (24" west), March 15 (13" west), March 19 (1" west), March 21 (5" east), March 25 (17" east), and March 31 (31" east). Iapetus shines at magnitude 10.1, about five times brighter than its minimum, when it lies to the west of Saturn.
The Cassini spacecraft continues its observation of Saturn and its many moons and rings. For the latest images from Cassini, see:
