At the exact same time, people at 4 positions on earth longitude 90 degrees apart will see sun on eastern horizon, sun directly above, sun on western horizon, and no sun at all.
Can someone show me on a FE map how people at 0,0 0,90 0,180, and 0, 270 can all see the sun at those angles at the same time? I got vectors pointing in wildly different directions.
What am I missing here?
