I actually can check sun's place on hour early mornings for there cause I had such project where I did calculated sun's position and tried to simulate scattering of light. I could check luminosity and infer early morning sports conditions by then I guess ☺

Of course I hadnt used n body problem first(were intending to add it in second iteration) . But went with Kepler model without solving n body problem. In first iteration of sun light scattering simulator stuff. So its a very crude simulator in that sense. But it can calculate the sun's position in sky for every lat long for world for any time as then. It's scattering had some issue to be fixed but weren't that much abnormal though were surely not werent working correct but not that much incorrect. 

Ok thinking solving n body problem might be also crude way of simulating it. Anyway.
