Há fenómenos astronómicos raros que vale a pena apreciar! Desde que se tenha possibilidade de estar em Manhattan em certos dias e que as condições atmosféricas estejam de feição. Sublime!

"On May 28 and on July 13, the sun will fully illuminate every Manhattan cross street (not the curved or angled ones) on the street grid during the last 15 minutes of daylight, and it will set on each street's center line. The sight is breathtaking. (...)
If the Manhattan street grid ran north-south and east-west, the alignment days would be the spring and fall equinoxes, the two days when the sun rises due east and sets due west. But the Manhattan grid is angled 30 degrees east from geographic north, shifting the days.
There are two corresponding mornings of sunrise right on the center lines of the Manhattan grid, (...) Dec. 5, 2006, and Jan. 8, 2007."
