We have finally arrived at the first 2023 official #Manhattanhenge sunset! The weather looks excellent so get your cameras ready. Are you wondering what this phenomenon is? Why it happens? Where you should watch from? I've got a whole thread for you on it #NYC @AMNH 
#Manhattanhenge is a name given to the days of the year when the sun sets perfectly aligned with the grid of Manhattan. So perfectly aligned with the cross streets where iconic buildings will beautifully frame the sun just as it touches the horizon. I also call it a "grid kiss"
Why does #Manhattanhenge happen? #NYC is a grid -- with 90 degree angles between the avenues and cross streets. At sunset you look west-ish across fairly wide cross streets and the Hudson river toward a relatively flat NJ skyline.
