does anyone have the time, date, longitude, latitude dependent
expression for a vector that points at the center of the sun. i'm
talking relative to local vertical, east and west as a coordinate
system.
i suggest as a derivation method to start with a inertial coordinate
system at the cener of the sun and convert.

It's interresting.
