From two of the windows in our flat in Cochin, the sunset at around 6 is visible, albeit with some structural interference. Nonetheless, the colors and hues, scientifically explained only two days ago, are visible from almost the entire city, or at least all the windows facing west.  As the seasons change, so do the sunsets – in February, the sun was a red ball of dull light without any spectral diffusion. In September (and now October), the sun sets a dull orange, and the entire sky looks like a beyond-hot mass of hydrogen and helium.
