5. The Night Sky Friday, January 31  In twilight, look very low above the west-southwest horizon for the thin waxing crescent Moon with Mercury to its upper left, as shown here. Saturday, February 1  Mercury now shines below the thin crescent Moon low in the west-southwest after sunset, as shown here.  Jupiter's moon Ganymede casts its tiny black shadow onto Jupiter from 5:42 to 8:22 p.m. EST. Jupiter's Great Red Spot crosses the planet's central meridian around 11:48 p.m. EST (8:48 p.m. PST). Sunday, February 2  In Taurus, in the familiar area of the Hyades, two lesser-known clusters await your scope — or even good binoculars if you have a dark sky. NGC 1647 and sparser 1746 lie exactly on the line from Aldebaran to Beta (β) Tauri (Elnath). Sky & Telescope Monday, February 3  The crescent Moon this evening shines to the left of the Great Square of Pegasus. The Great Square is tipped up onto one corner, as it always is at this time of year. Tuesday, February 4  Jupiter's moon Io disappears behind Jupiter's western limb around 8:57 p.m. EST. Twenty minutes later, Jupiter's Great Red Spot crosses the planet's central meridian. Finally, Io reappears out of eclipse from Jupiter's shadow, just east of the planet, around 11:56 p.m. EST (8:56 p.m. PST).
