The Night Sky for the Week of 1-21-24

Some interesting astronomical events are happening this week. On Sunday, the gibbous Moon will be between Aldebaran and Capella. Later that evening, Jupiter's Moon, Io, will cross onto Jupiter's face, followed by its shadow. On Monday, the Moon will be in a starry area of the winter sky. On Tuesday, the Northern Cross in Cygnus will be nearly upright in the west-northwest right after dusk. On Thursday, the Full Moon will form a line with Procyon and Sirius. On Friday, the equilateral Winter Triangle will be visible in the southeast, and Mercury and Mars will have a difficult conjunction just above the southeast horizon at dawn. Finally, on Saturday, the Winter Hexagon will fill the sky toward the east and south.
