Also check the elevation for point 3102. Back on page 2 of this post you posted a file with #3102 Elev=1003.03'. Your Excel file has Elev=1003.30'?
My latest sketch is based on the coordinates in your latest Excel file. Are the eastings and northings reversed in that new file?
Here is an update on my previous "Sketch 04". Your latest Pathways.xlsx file has the coords in East / North. Previously I entered your data as North /...

Pretty cool calculator. I have no plans to do a sun shot but it is nice to know about some of the resources.
3 weeks a go, Oct 24, there was a post named "Shoot The Sun". There was an Ephemeris page as some other stuff you might like.
@mightymoe DOT multiplied grid coordinates by the scale factor, so we continued with that system. That is not correct in my area becau...
