A space weather kind of holiday…. “A special full moon, the smallest of 2004, will brighten the nights around Christmas.” Also, “on Christmas morning and every morning after that for more than a week, you can step outside at dawn (between about 5:30 AM and 6:00 AM) and see all five naked-eye planets: Mercury, Venus, Mars, Jupiter and Saturn. Facing east you’ll find Mercury and Venus hovering together near the horizon. Mars and Jupiter are there, too, but higher up. Spin around to locate Saturn. It’s setting in the west along with the full moon.”
