Hi, jmr.

Your AP is N48. You are N of the equator.

Dec = S26. The body is S of the equator.

then, Latitude is contrary to Declination.

Using your figures, I come up with Hc = 7* 51.9'

Intercept = Away 37.8' nm.

Z = 145*
Zn = 215*

You did good, but after a good night's sleep, you'll find it'll all work out

btw: my copy of HO 229 vol 4 (45* - 60*) p. 81, under 48* Lat & across from Dec. 26* shows:
Hc= 8* 08.5, d= -54.4, Z= 145.2*
North Lat then LHA < 180, then Zn= 360 -Z
