Further to my earlier post this evening, the little grey cells (lgc) are waking up again. I see I misled you slightly. I actually needed to find the co lat of the point where the GC lies E/W before finding the longitude where it occurred, so that's what you were looking for (I think). Please see the bottom of page 4 and the top of page 5 in the photos below, but please don’t ask me to explain. The lgc are not that far awake yet. DaveP
