Just as the ancients watched the celestial bodies align with their own primitive rock formations, New Yorkers celebrate those rare occurrences when that mysterious orange orb known as the sun sets along Manhattan's street grid. Rejoice! For Manhattanhenge, is upon us.

While this evening's sunset will only feature the sun partially visible between the skyscrapers, tomorrow the full effect can be seen from any East-West Manhattan street. Don't deprive your 58 Instagram followers of this special opportunity.
