We have at last attained peak moon phase naming:
Rare Black Moon to rise on Friday in night sky of Western Hemisphere
So, it’s a second new moon, happens once every couple-three years, and you can’t see it. Not unusual, not rare, not visible. Got it.
“Rare” used to describe something common like this is related to the fact that teasing, please-click-me headlines that ask a question can nearly always be answered “No” and “arguably” in a news story almost always means “It’s not true that…”
My sincere apologies to Creedence Clearwater Revival for associating them with this.
