Hi

It may be interesting to have the sun on the horizon.
Azimuth 90 °, 92 ° Zenith are the values set in Indigo standalone application in the image below.

I suppose that's entirely possible once you've reached a height of 15 - 20 km where the curvature of the earth starts to become evident. But then the sun-sky system doesn't simulate those kind of heights very well anyway.
