    Antoine,

    A Palm Pilot smart phone returned the following results (rounded to nearest minute):

    UT 03:50:49  5/13/2016

    aLat 47° 00' N  aLon 122° 32' W°  (Flt. Track Data)

    GHA 238° 37'

    LHA 116° 5'

    Dec 18° 28' N

    S.D. 16'

    Hs 0° Upper Limb Sun

    Hc 356° 59' (- 3° 1' )

    Ho             (-3° 1' )

    Int 0°

    Az 301.5°

    Appx. Temp -5° C (f= 1.0)

    Alt 12788 ft (3875 M)

    Dip .97(sqrt 12788) = -110'

    refraction by pub 249 table 6 = -55'

    Total corr.: Upper Limb S.D.+Dip+Ref. = -181' (-3° 1')

    note-there is no coriolis correction since a bubble octant wasn't used.
