This is Ephemeris for Wednesday, January 17th. Today the Sun will be up for 9 hours and 14 minutes, setting at 5:30, and it will rise tomorrow at 8:15. The Moon, at first quarter today, will set at 1:28 tomorrow morning.
Let’s find out where the naked-eye planets have wandered off to this week. Four of those five planets are now visible. Saturn and Jupiter are the evening planets. Saturn can be seen moving from low in the southwest to setting in the west-southwest at 8:42 pm. Jupiter, left of the Moon tonight will move from high in the south to set in the west-northwest at 2:05 am. Venus, the brilliant morning star, will rise in the east-southeast at 5:58 am, and be a brilliant beacon in the morning, shining in the southeast before the bright morning twilight claims it around 8 am. Mercury will also be visible below and left of Venus, and should be visible by 7:30 am. Mars is below left of Mercury, but really is too dim to be seen.
The astronomical event times given are for the Traverse City/Interlochen area of Michigan (EST, UT –5 hours). They may be different for your location.
Addendum
Jupiter, Saturn and the Moon around 7 this evening, January 17, 2024. Jupiter appears brighter and bigger than the Moon, but isn’t. The blooming of the image of stellar type objects is to make them look brighter. The Moon though brighter is shown at its actual apparent size. They look much nicer in the real sky. Created using Stellarium.
The moon tonight about 7 pm this evening, January 17, 2024, as it might appear in binoculars or a small telescope, with selected features labeled. Created using Stellarium, LibreOffice Draw, and GIMP.
Venus and Mercury as they might appear about 7:30 tomorrow morning, January 18th 2024, in the growing twilight. Created using Stellarium.
