Twice a year, Manhattanhenge, or Manhattan Solstice, occurs and the sun aligns perfectly with Manhattan's street grid.
If you happen to be in the Big Apple during New York's spectacle in the sky, get your Instagram ready to snap some shots (#nofilter, though, naturally).
However, there will probably be a bunch of other people doing the same thing with you because it's just too beautiful not to want to share with everyone.
Tonight, the first instance of the summer will take place. If you miss it, no worries — the second Manhattanhenge takes place on July 12. Check out everything you need to know about tonight's Manhattanhenge and take a look at last year's photos below.
