Sree Padmanabhaswamy temple and equinox sunset

co-orindate: 8.4828° N, 76.9436° E

It is located just ~8 degrees north of Equator, so during equinox, the sun sets almost vertically.  

the temple is ~35 m wide, 35 m tall. the five stories with doors are roughly 21 m apart vertically.

Half hour before equinox sunset, azimuth is 269 degrees

Equinox sunset, azimuth is 270 degrees

So if the window is enough wide, then sunset will appear in all 5 windows

say 200 m away from the temple, the sun travels in horizontal distance = tan ( 1) * 200 = 3.5 m.

But there are only 5 windows in this 7 story building, so the sun travels through these windows  3.5 x 5 / 7 = 2 m horizontally 

from photo, widest window(at first floor) is only around 1.4 m wide, so the windows are very likely not vertically aligned, but tilted by say 0.5 degrees along north-south direction, or 0.6 m horizontally.

Watch the youtube video above 0:48 - 0:55

 

please note the windows are not the same sizes,  most narrow at top floor, and wider when you go down each storey.

The best spot to take equinox sunset photo is 227 m to the East of the temple:
