Formula is: LHA body = GHA body - west DR long. So if GHA = 1deg. 24.4',
then LHA = 1 deg. 24.4' - 38 deg. 59.4' W.

(Then, assuming that GHA which you calculated is correct):

You'll need to add 360 deg to the GHA before subtracting the 38 deg. 59.4'
W, which gives:
361 deg. 24.4' - 38 deg 59.4' = 322 deg. 45.0' --- but...
if you are using sight reduction tables (marine or air) and need a
whole-degree LHA, then the assumed long. would be 38 deg. 24.4'W so that 361
deg. 24.4' - 38 deg. 24.4' W, giving LHA star = 323 deg. 00.0'

(did you use the formula, GHA star = GHA Aries + SHA star to get GHA star?)

Russell
