Oops, my error it is discussed in Hew's Lat and Long by Noon Sight(sorry Hew!) in Chap 11.

Hi Gary, thanks for that and oddly enough, unless I missed something, this method is not mentioned in Hew Schlereth's "Latitude and Longitude by the noon Sight" and other books! One otherwise excellent book in particular "Celestial Navigation" by Tom Bottomley does give the classic AM and PM curves with Hs and time but NOT equal altitudes. He relies on the peak of the curve. On the equal alt method several pairs are taken. I do not remember which book this was in possibly Hew Schlereth's "Cel Nav in a Nutshell"?
