Celestial Navigation

I need some expert, or, least competent help with a CNav question.  One relates to the book "Celestial Navigation" by Burch and one from the book "Practical Celestial Navigation" by Howell.  There are two problems in the texts, one with an LHA/body of 092 degrees and one with an LHA /body of 094 degrees.  I use H.O. 229.  Because of the way H.O. 229 is laid out these two LHAs are not in the tables.  I am trying to figure out what pages of H.O. 229 to use when the pages don't exist.

I know I am missing something obvious here but I have unable to locate the same numbers for Hc, d, and Z that the authors of the texts obtained.  I know there is an obvious, very simple answer to this and I will be embarrassed when I am told the answer but my frustration with this issue has reached critical mass and I'm afraid of an accident - a text spontaneously catching on fire, my dividers suddenly disintegrating - something like that. 

I have been trying to learn Celestial Navigation because I enjoy sitting on the beach with my sextant and a beer answering questions from passersby.  Almost as good for meeting women as having a really cute dog.  (Right, wishful thinking).  Nothing to do with actually navigating, although I'd like to give it a shot one day, with adequate backup (4 or 5 GOS units open board).

Anyway, if someone can help an old dog learn a new trick I would eternally grateful to the point of buying you a beer if you ever end up in my neck of the beach. 

If corresponding by email would be easier I can put my spam address out there.

Thank you

I don't use HO 229 to reduce my sights, but I'll research the issue and maybe I can figure something out.

In the meantime, feel free to correspond with me at my message box here, (HenryC)or at my home address (check your messages).  I live in Fort Lauderdale.

Don't anyone spend any time on this (just assuming anyone was actually going to do so) - I was informed of the answer.  If you are familiar with H.O. 229 you'll know how dumb my question was.

This does point out the dangers of tunnel vision.  I was doing problems and they had all used the LHAs at the top of the pages.  I got so locked into that that I completely overlooked that each page has a bottom margin as well as top margin.

Flexibility and adaptability are the keys to sailing, survival, and navigation.  I hope no one moves this old dog's food bowl, I'll never find it again.
