Every evening in the summer, sunlight pours through the west-facing windows in our apartment. As the sun sets over the Hudson River, it lights up the living and dining room and bathes the hallway in orange light. I’ve always perceived the effect to be most powerful in late summer, but apparently it’s best this time of year. Naturally, it’s not just 60th street that sees this beauty, but all the cross streets in Manhattan. And I just learned there’s a name for this phenomenon, which occurs perfectly tonight.
