Byron:I just worked out the problems of Time verses bearings. Amount of time pass
for bearings.
Using July 12 Dec of 22 degrees, Lat 45N Long 0 at 10 the sun was at brg 124 Ht 56
at 15 brg258 HT45 the 5 h the sun changed brg by 134 degree. Not 75.
The same 22 degrees Dec, but Lat 45 and Long 70W at 10 the Sun was 067 HT 3 degrees
at 15 the Sun was brg 067 HT 3 degrees for a change brg of 58 degrees.
AT Lat 25N with the Sun Dec at 22 GMT 10 brg 090 HT 62 and at GMT 15 brg 276 for a change of 186 degrees.
Same as above at 05 GMT 060 at 10 090 for a change of 30 degrees.
I didn’t try for real accuracy just rough figures. So the Sun Dec. the LONG.
The Lat. Are all considered. The 15 degrees each hour is a good estimation
but far from the angle.Like a ship far off coming toward you, change brg slowly depending on course speed and distance.the view easy to see and understand.
