Juan Manuel Pérez Rayego in Mérida, Mexico wrote on January 15, 2018: “Mercury down, moon and Saturn above, before a cold dawn.”
As 2018 opened, the planets Jupiter and Mars were closing in on each other in the morning sky. On January 7, 2018, they came spectacularly close – only 0.25 degrees apart – or about half a moon-diameter. On January 10-12, 2018, the waning crescent moon swept past Mars and Jupiter. This weekend, the moon is moving downward in the predawn sky, preparing to sweep past Saturn and Mercury.
