# EXERCISE 31 — INTERCEPT SUN (Numerical Solution)

###### GMT   – 04 March 22h 55m 40s

GHA (04d 22h)         147˚  06.9’                                           Dec         S  06˚  01.3’
Incr. (55m 40s)        013˚  55.0’                                            d(-1.0)                00.9’
GHA                          161˚  01.9’                                             Dec        S  06˚  00.4’
Long (E)              (+) 151˚  10.0’
LHA                         312˚  11.9’                                              Lat               38˚  11’ S

P = (360˚ – LHA)
=  ( 360˚ – 312˚  11.9’)
= 47˚  48.1’

• Rohit Chavan says:

I guess in sum no. 2 the CZD is 70d 28.4m and not 70d 28.9m

• Chris says:

I think your example 5 is incorrect. the LHA is 46 31.5 but in your ABC calculations you have used 47 31.5. also your Tan AZ of 2.705 is incorrect.

I believe the correct AZ is 290.2 degrees

• Harry says:

I believe correct LHA is 47° 30.5′
My intercept is coming- 10.5° towards
True Az- 289.5°
