Mercury reaches Greatest Western (Morning) Elongation on the 1st and is visible low in the SE sky a half hour before sunrise. Appears near Saturn on the 13th.

Venus arrives at superior conjunction on the 9th and is not visible this month.

Mars, in Libra, rises 4 hours before the sun all month. It appears in the same binocular field with Jupiter for the first half of January, being closest (0.2o) on the morning of the 7th.

Jupiter, also in Libra, moves away from Mars by mid-January and rises before 2am at month’s end. 

Saturn is emerging from last month’s conjunction, reappearing in the morning sky early in the month. Its January 13 conjunction with Mercury will require binoculars and an open view of the SE horizon.
