Hi, I've just found my notebook with the solutions to the problems. I worked the sights with the classical haversine method and got the following intercepts: Kochab -1.9 Az 339 Rasalhague -14 Az 233 Alkaid -5.6 Az 311 Altair -4.1 Az 176 Venus +10.1 Az 97.5 Moon +4.4 Az 150 This gave me a fix at 40 13.5 N 49 58.5 W, which is practically identical to the solution given by the book. Hope this can help.

Speaking of the moon... I am working through Leonard Gray's book One Hundred Problems in Celestial Navigation. I calculated and plotted all the sights for the stars, the moon's lower limb, and Venus for the first problem (1-1). My solutions for the stars and Venus seem OK, but my line-of-position for the moon seems quite a ways off. I get a pretty good solution without the moon (not more than one minute off of the given answer, and that's using an 8.5 x 11 plotting sheet). Is there anyone that has saved their solution to this in notes somewhere? I would like to see if it is supposed to be so far off, or if I left out one of the many corrections for the moon. The stars using Pub 249 were sure much easier! Secondly, does anyone know of any online celnav worksheet forms? I downloaded the ones by Harold Arsem from the celestialnavigation.net website, but I thought I would find more on the internet than just a couple forms.
