Rare blue moon makes appearance

LOS ANGELES — The saying “once in a blue moon” refers to something that’s exceedingly rare. But there were actually two chances to see this lunar occurrence today, when a so-called blue moon is in view.

The first opportunity was in the morning — yes, this morning — as the blue moon set for the day, said Anthony Cook, astronomical observer at Griffith Observatory.

You’ll get a second chance to see the blue moon, when it rises at 7:13 p.m. PDT.

So what is a blue moon? It’s the second full moon within one calendar month.

The moon isn’t actually blue. And it might even take on an orange hue as it starts to rise in the sky, Cook said. If anything, the Friday night moon will most likely appear an especially brilliant white.
