    Attached are time sight reductions and a Sumner plot for the recently posted Sun Moon observations. I attempted to plot as Frank described on graph paper.  It seems to work. For Jeremy to get a Sumner line down on the electronic chart I would try entering Sumner lats/lons as way points with resulting course tracks crossing for a fix. Probably easier to use graph paper and then just enter the position as a fix.
