Canopus is an interesting "Limit Case".
The track below is for no-wind 480 Knots Ground Speed, and represents the most south westerly track possible if "steering by Canopus", determined by the limiting requirement that Canopus must always be on - or above the horizon, to be seen. The minimum elevation is "mid flight", around 21:30 Utc, as shown in the right most column below.
The terminus is 37 South 69.75 East.
I would be interested to see what Mike Chillit's "drifters" do if starting from that position.
