In the early hours of January 7th 2018, Mar and Jupiter will appear to be very close in the sky in the constellation of Libra. At 05:00UT they will be 13 arcseconds apart, but only 11 degrees above the horizon. Should make for an interesting view through binoculars or a small telescope. Astronomical dark ends at 06:09UT (Sunrise is 08:11UT) that morning so you could wait till a bit later when they will be bit higher in the sky. See the picture below for where to look.
