About One Day in Chennai
What happens
The sun is placed with the NOAA solar position formulas for Marina Beach, including the bending of light near the horizon. Sunrise and sunset are when the middle of the sun is 0.833° below the horizon.
The sky colour comes from how air scatters sunlight: blue light scatters most, so the sky is blue overhead and sunlight turns orange through more air at sunrise and sunset.
You stand on the sand east of the Ice House. The Lighthouse, Ice House, University of Madras, High Court, LIC Building and Central Station stand at their real compass directions from there. Their heights are drawn three times taller, and the sun six times bigger, so you can see them.
A 1 m stick’s shadow is 1 ÷ tan(sun height) long. Around 24 April and 18 August the noon sun is almost straight overhead in Chennai, and the shadow almost disappears.
The Chennai bit
The sun rises out of the Bay of Bengal and sets behind the city. Morning walkers on the Marina see it first.
