Cloudy weather could spoil the fun for a solar phenomenon in the city Monday night.
"Manhattanhenge" is when the sunset aligns exactly with Manhattan's east-west numbered streets.
It creates unique photo opportunities, like this one from a couple of years ago.
If the sun's out at all tonight, you'll be able to see the half of the sun at 8:13 p.m.
The sun will then fully allign and be visible Tuesday at 8:12 p.m.
The term "Manhattanhenge" is a play on Stonehenge, where the sun aligns with the stones on the sunrise of the summer solstice with a similarly dramatic effect.
