Crowds flooded Midtown Manhattan streets this week to photograph the bi-annual Manhattanhenge sunset as the sun aligned with the city's street grid [1].

The event draws thousands of residents and tourists to the U.S. city's center, turning a functional urban layout into a massive open-air gallery. Because the alignment creates a striking visual effect between skyscrapers, it has become a significant cultural and photographic moment for New York City [2].

Manhattanhenge occurs when the setting or rising sun aligns with the east-west street grid [3]. This specific alignment creates a spectacular skywatching event that happens twice a year, typically in late May and early July [1].

Observers gathered in Midtown on Thursday evening to capture the phenomenon [4]. Other sightings were reported earlier in the week on Monday and Tuesday [5]. The sunset time for the event this week was approximately 8:20 p.m. ET [6].

"Get your camera ready because Manhattanhenge is making a comeback this week," a reporter from KDVR said [7].

The phenomenon is a result of the city's specific geographic orientation. "Manhattanhenge occurs when the setting (or rising) sun aligns with the city's east-west street grid, creating a spectacular skywatching event," the CBC Interactive Team said [3].

Visitors filled the streets on May 29 and May 30 to witness the light bathing the urban canyon in gold [8]. The event typically results in heavy pedestrian traffic in Midtown as people compete for the best vantage points to photograph the horizon [4].

Manhattanhenge demonstrates the intersection of urban planning and astronomy, where the rigid Commissioner's Plan of 1811 creates a predictable celestial alignment. The event's growth in popularity reflects a broader trend of 'astrotourism' within metropolitan areas, where residents seek natural phenomena within a dense concrete environment.
