    What happens if you choose a longitude that makes LHA 359?

    It is not a question of whether you need H.O. 208 or not, rather how it should/could be used with an LHA of zero.  Please send the LHA 360 page (as I now understand it, based on the pages you previously sent, there is an LHA 360 column but not an LHA 0 column) when you get a chance.

    Um, you do realize that with an LHA of zero you don't need HO 208, you just do the normal noon sight computation. Simple addition and subtraction.

    The results have improved for my use of Ho 208 but an ususual case is giveing me trouble.
    With a GHA of 478* 49.8 and assumed Lon of 118* 49.8 the LHA is 360 or zero.
    My circa 1940 .pdf does not have a zero LHA column. If I use 360*60.0' the results are way off. Plugging my sight data into the Ho 208 calculator called "Celestial Tools" I got an intercept of over 1000 miles.
    Sight data:
    Date 22 Feb
    Time 20-29-06 PDT
    ZD +8
    Hs 37*57.5 (Already corrected for AH use)
    SHA 258* 33.21
    GHA Aries 212* 58.5
    Ref. -1.3
    IC -0.4
    USNO reduction shows Hc 37*56.1 and intercept of 0.3
    As a post script, does anyone have a .pdf version of Ho 208 that has the extra column headings at the top and bottom for 90-180, 180-270 etc.?
