Externet Posted December 5, 2006 Share Posted December 5, 2006 Hi all. Now i got confused; this site: http://www.mathopenref.com/subtend.html shows the subtended angle for the sun being 32 arc minutes or 0.52 degree. That seems very small. Does it mean that in a 12.0 hour day, the sun path could be drawn as 346 sun disks fitting edge to edge on the sky ? Am trying to create a formula, chart or nomograph to calculate the needed diameter of a distant mirror reflecting the entire sun disk. (As a heliostat of what diameter positioned at a given distance will show the complete sun disk) Miguel Link to comment Share on other sites More sharing options...
