How do I calculate the date when the sun passes to the top of this building?
Hi, the
I live in Singapore and there is a high-rise building 5km away from my apartment, which has a hole in the middle (25X20 meters rectangle). Is it possible to calculate the dates when sun rises, I can see the sun inside the hole from my apartment? (Let's not consider the likely bad weather for now). FYI, now, the sun passes a building three blocks away, but no hole in it. |

20 M at 5000 M = 20/5000 radians = 0.004 rad
= approx 0.228 degree Sun's diameter = 0.5 degree , so it wont fit within the hole. |
