A brilliant moon should be all that Rudolf needs to guide Santa’s sleigh over the Pacific Northwest this Christmas. For the first time in almost four decades, a full moon will hang high in the sky, making the landscape glow – especially where there is snow.
“Not only will the moon be full, but it also will be directly overhead. With a break in cloud cover, it should make for impressive viewing,” said Guy Worthey, associate professor of physics and astronomy at Washington State University.
