The Baltimore Sun

Tonight's full moon if the Long NIght Moon, the last before the winter solstice on the 21st. And it's a honker. It occurs just hours before the moon's closest approach to Earth (perigee) this year, making it appear larger than most full moons. It's also the closest perigee -- 231,559 miles -- in the past 15 years, or the next eight. When the full moon and extreme perigee coincide, we should expect unusually high tides.
