and of course if you wan’t something cleverer than a simple latitude shot, you probably need 1998 values to start off with. DaveP

Having spent a fairly futile hour wading through APs 3270, I remembered that several months ago I’d bought a computer programme called Navigator, so I thought I’d check my working against that.  The  figures for 00.00 Tuesday 8^th Sep were as follows:

Aries                GHA
Year                 ddd mm.m
1998                347 50.4
2002                347 52.2
2006                347 54.3
2010                347 56.4
2014                347 58.1
Difference 1998 to 2014 GHA Aries 7.7’, I guesed 6’

Polaris              GHA                Dec
Year                 ddd mm.m        dd mm.m
1998                310 28.8          89 14.0
2002                309 43.1          89 15.1
2006                308 45.1          89 16.4
2010                307 34.4          89 17.4
2014                306 28.2          89 18.4

Difference 1998 to 2014 GHA Polaris 4° 00.6’ SHA Polaris 3° 52.9’ Dec Polaris 4.4’, a significant difference due to P&N changes. It ougt to be possible to work out a Q Table knowing SHA and Dec Aries for a particular year using polar graph paper, but I'll leave that to the mathematicians
