In recent years people have made a big deal of “Manahattanhenge,” the otherwise astronomically insignificant day when the rising or setting sun happens to line up with the Manhattan street grid.

But there is another street grid in this city that lines up with the rising and setting sun at a no less astronomically auspicious time than the summer and winter solstices.   I’m referring to the street grid that begins on Garfield Place in Park Slope and extends down to Windsor Place/Sherman Street in Windsor Terrace.

The angle of the east-west streets is slightly different starting with Carroll Street to the north, and Prospect Avenue to the South. But those in between and on the Park Slope side of the terminal moraine will find the sun setting straight down the street on the summer solstice. For those on the Windsor Terrace side, the sunrise was right down the street on the winter solstice. It was about that time last year that I figured this out, following my curiosity and messing around with this site, and went out and checked.
