Perigee makes the Old Moon look bigger


Yes, that was a full moon last night. It was the first since the winter solstice, so that makes it the Moon After Yule, or the Old Moon.

It would be nearly as full tonight, if you could see it. Skies should clear by Friday night.

And if the moon looks unusually big to you then, that’s because it will be at perigee – its closest approach to Earth this month.

On Mar. 19, the closest lunar perigee of the year will occur simultaneously with the full moon. Watch for unusually high tides.
