Saturday we have a full moon. There will be plenty of talk about this being a Blue Moon, the second full moon of the month. We call this the Mud Moon, a name that is best suited for the season.

Tides this weekend will seem more extreme this weekend. The moon was in perigee on Monday, its closest to the Earth in the month.

Two brilliant planets are close together in the morning sky. Mars and Saturn are low in the southern sky, both in the zodiacal constellation Sagittarius. Mars is distinctly red compared to the yellowish Saturn. On Monday morning they are closest, only 1.3 degrees apart. For much of April, the two planets will be impressively close, though not as close as next week.

Though apparently close. Mars is 102 million miles away and getting closer. Saturn is nine times farther away from us at 920 million miles.
